If you've ever crouched over a nearly-finished amigurumi, safety eye in hand, wondering exactly where to push it through — you're not alone. How to attach safety eyes and safety noses is one of the most commonly asked questions in the amigurumi community, and for good reason. Get it right and your plushie looks polished, professional, and ready to fall in love with. Get it wrong and you risk a lopsided gaze, torn stitches, or an eye that pops loose over time. This guide walks you through every step of the process so your finished amigurumi is both beautiful and durable.
Understanding Safety Eyes and Safety Noses: What Are They?
Safety eyes are two-part plastic components used in stuffed toys and amigurumi. The front piece is a shank-backed eye (usually with a colored or clear iris) and the back piece is a flat plastic or metal washer that locks onto the shank. Once the washer clicks past the ridges on the shank, the eye is secure and cannot be removed without damaging the fabric.
Safety noses work on the same principle — a shaped front piece (triangular, oval, or round) with a shank and a locking washer. Both eyes and noses are called "safety" components because when installed correctly, they are extremely difficult for small children to pull off, making them much safer than sewn-on buttons or glued beads.
The most common sizes for safety eyes range from 6mm (perfect for miniature amigurumi) up to 18mm or even 24mm for large statement pieces. Safety noses typically range from 9mm to 18mm. Choosing the right size relative to your finished piece is part technique and part creative choice — which we'll cover below.
Tools and Materials You'll Need to Attach Safety Eyes
Before you start, gather everything at your workstation. Having the right tools makes the difference between a smooth process and a frustrating struggle.
- Safety eyes and/or safety noses — in your chosen sizes and colors
- Washers — the locking backs that secure the eyes; always keep extras on hand
- Yarn needle or tapestry needle — for marking exact stitch placement
- Stitch markers — helpful for counting rows and marking eye position
- Chopstick or blunt dowel — for pressing the washer down firmly onto the shank
- Pliers (optional) — some crafters use flat-nosed pliers wrapped in tape to press washers extra firmly on larger safety eyes
- Polyfill stuffing — have it nearby, because you'll insert eyes before the final closure
- Good lighting — positioning eyes accurately requires seeing your work clearly
One often-overlooked supply is the washer itself. Standard plastic washers work well for most projects, but if you're making toys for young children, metal washers provide even more holding strength. You can browse our selection of premium washers to find the right locking back for your safety eyes and noses — having the right washer for the right eye size really does matter.
How to Attach Safety Eyes: Step-by-Step
Follow these steps for a clean, secure attachment every time. This method applies to both eyes and noses.
- Finish your head piece (but don't close it yet). Safety eyes must be inserted before you finish stuffing and close the head. If you've already closed the piece, you'll need to reopen the seam — so always plan ahead.
- Mark your eye positions. Use stitch markers or pins to mark where each eye will go. Take your time here — even one stitch off can make an eye look dramatically different. Most amigurumi designers give a row and stitch count for eye placement; if you're freestyling, a good rule of thumb is to place eyes on the widest part of the head, typically between rounds 8–12 depending on your head size.
- Check symmetry before you commit. Hold your head piece up and look at it from the front. Do both markers look even? Swap the piece from hand to hand and check again. It's very easy for one eye to creep higher or lower without you noticing. A mirror can help you spot asymmetry quickly.
- Insert the shank through the fabric. Using the tip of a yarn needle, gently separate — not cut — the stitches in the stitch you've chosen. Push the shank of the safety eye through this gap. The stitches will stretch around the shank; if you've used a tightly crocheted fabric (which is best for amigurumi), this takes a bit of firm pressure. Do not pierce the yarn — always go through the natural gap between stitches.
- Attach the washer. From inside the head, push the washer onto the shank with the ridged side facing the inside of the shank. Press it down firmly — you should hear or feel a series of clicks as it locks over the ridges. Continue pressing until the washer won't go any further and the eye is flush against the fabric from the outside.
- Test the eye. Grip the front of the eye firmly and try to turn and pull it. A correctly installed safety eye should not rotate or pull out. If it feels loose, press the washer down further or replace with a tighter-fitting washer.
- Repeat for the second eye and any nose. Always test both eyes before you stuff and close.
- Stuff and close. Once eyes and noses are secured and tested, proceed to stuff your piece fully and close the opening.
How to Attach Safety Eyes Without Damaging Your Crochet Fabric
One of the most common fears among new amigurumi makers is that inserting a safety eye will tear or distort the crochet fabric. With the right technique, this simply won't happen.
Always Separate, Never Pierce
The cardinal rule: never pierce the yarn itself with the shank. Always push the shank through the space between stitches. Crocheted fabric is made up of interlocked loops, and the natural gaps between stitches (especially in single crochet amigurumi fabric) are the correct insertion points. Use a yarn needle, bobby pin, or even the shank tip itself to carefully locate the gap between two stitches before inserting.
Choosing the Right Stitch for Eye Placement
The ideal stitch for eye placement is one that sits in the center of a flat section of fabric — not on a row increase or decrease. Stitches around increases and decreases are already under tension, and adding an eye shank there can distort the shape of the piece. When possible, choose a stitch in a straight round of the body.
Avoid Twisted Yarn
If you're using a ply yarn (multiple twisted strands), inserting a shank incorrectly can split the plies and weaken individual strands. Using a tight single crochet with a small hook reduces the stitch gap slightly but makes each stitch more resilient and consistent.
Test on a Swatch First
If you're new to safety eyes or trying a new yarn type, crochet a small test swatch first and practice inserting a safety eye. This lets you feel the correct resistance and technique without risking your finished piece.
Safety Eye Placement Tips for Beautiful, Expressive Faces
Technically secure eyes are only half the equation — placement is what gives your amigurumi personality and charm.
The Distance Between Eyes
Eyes that are too close together make amigurumi look narrow and rodent-like. Eyes that are too far apart can look surprised or unfocused. A classic rule is to leave 3–5 stitches between the inner edges of the eyes for a head that's 20–30 rounds tall. Adjust upward for larger heads.
High vs. Low Placement
Placing eyes high on the head (closer to the top) creates an innocent, childlike look — very common in kawaii style amigurumi. Placing eyes lower and closer to the center creates a more adult or lifelike appearance. For cute critters, aim for the upper third of the face.
Angle and Tilt
Eyes don't have to sit perfectly horizontal. Tilting the eyes slightly inward (so they angle toward a central nose point) creates an endearing, puppy-dog expression. This is especially effective with oval safety eyes.
The Nose Anchor
If your pattern includes a safety nose, place it before finalizing eye positions. The nose acts as a visual anchor for the face, and eyes should be positioned symmetrically relative to the nose, not just relative to each other.
Use Pins or Stitch Markers to Preview
Before committing, use T-pins or stitch markers to mock up the eye and nose positions. Take a photo with your phone and review it — photos often reveal asymmetry or imbalance that's hard to see when you're holding the piece.
How to Attach Safety Noses: Specific Tips
Safety noses work identically to safety eyes in terms of mechanism, but there are a few specific tips that make nose placement smoother.
Choose the Right Nose Shape for Your Animal
Triangular noses work well for cats, bears, and dogs. Oval noses suit bunnies and larger mammals. Round ball noses are classic for teddy bears and soft toy styles. The shape you choose dramatically affects the "species" read of your amigurumi, even if the head shape is identical.
Center the Nose Precisely
The nose sits on the vertical center line of the face — finding this line is critical. Count the total number of stitches in the round where you'll place the nose and divide by two to find the exact center stitch. Mark it with a stitch marker before inserting.
Nose Placement Relative to Eyes
A general guideline is that the nose should sit 3–5 rounds below the eyes (for a standard round amigurumi head). Too close and the face looks compressed; too far and the muzzle area looks elongated. Experiment on your test swatch before committing.
Double-Check Orientation
Triangular noses can be installed right-side-up or upside-down, and both look slightly different. Some crafters prefer the point facing down (classic teddy bear look); others prefer point up (creates a softer, rounder nose impression). Make sure both nose orientations are considered before you click the washer in place.
How to Attach Safety Eyes to Knit or Woven Fabric (Non-Crochet)
While this guide focuses on amigurumi (crocheted), safety eyes can also be used in knitted plushies and sewn stuffed animals. The technique is similar, but there are a few differences.
Knit fabric is looser and more elastic than crochet. This means the stitch gaps are larger and easier to penetrate, but it also means the fabric provides less resistance to the shank — and less fabric to grip. For knit fabric, always use a metal washer rather than a plastic one, and consider adding a small felt circle behind the washer inside the piece to distribute the holding force over a larger area of knit fabric.
For woven fabric (felt, fleece, or sewn plushies), pierce through the weave of the fabric directly with the shank. The fabric's own structure will hold the shank in place. Again, a felt reinforcing circle or metal washer gives extra security.
Safety Eye Sizing: How to Choose the Right Size
Matching eye size to your finished piece is part technical and part aesthetic. Here's a quick reference guide:
- 6mm eyes: For mini amigurumi under 3 inches tall, finger puppets, and fine detail work
- 9mm eyes: A versatile mid-size for small animals 3–5 inches tall
- 12mm eyes: The most popular general-purpose size; suits most standard amigurumi (5–8 inches)
- 15mm eyes: Great for larger amigurumi, expressive characters, and cartoon-style proportions
- 18mm+ eyes: For large plushies and statement pieces; creates a big, soulful gaze
When in doubt, cut eye-sized circles from paper and hold them up to your work-in-progress before purchasing. This simple trick saves a lot of trial and error.

Common Mistakes When Attaching Safety Eyes (and How to Fix Them)
Mistake 1: Installing Eyes After Closing the Piece
The most common beginner mistake. Safety eyes must go in while the piece is still open. If you've closed your piece, you'll need to carefully pick out the closure stitches to reopen it. Prevention: always read your pattern through before starting and note the eye insertion step.
Mistake 2: Choosing a Stitch That's Under Tension
Stitches at increases, decreases, and color changes are under more tension than plain stitches. Inserting an eye here can distort the fabric. Choose a plain stitch in a straight round for best results.
Mistake 3: Not Pressing the Washer Far Enough
A partially-seated washer will allow the eye to rotate or wobble, and with enough force can be pulled out. You must press the washer past all the ridges on the shank. Use a chopstick, dowel, or wrapped pliers if your fingers aren't strong enough — especially important for larger safety eyes where the shank is thicker.
Mistake 4: Asymmetrical Placement
Even experienced crafters rush the eye placement step and regret it. Always take the time to check and double-check symmetry before installing. Once the washer is clicked into place, the eye cannot be removed without cutting it out or damaging the shank.
Mistake 5: Using the Wrong Size Washer
Each safety eye shank has a specific diameter, and the washer must match. An undersized washer won't click on; an oversized washer won't grip securely. Always use the washer provided with your safety eyes, or source matching replacements from the same supplier.
Making Amigurumi Safe for Children: Extra Precautions
If you're making amigurumi as gifts for children under 3, safety eyes — despite their name — are still a choking hazard if improperly installed or if the fabric is damaged. Here are extra precautions for child-safe amigurumi:
- Use metal locking washers instead of plastic for maximum grip
- Always tug-test each eye vigorously before gifting
- For infants and children under 18 months, consider embroidered eyes (no hardware at all) as the safest alternative
- Use a tightly crocheted fabric (small hook relative to yarn weight) to minimize gaps around the shank
- Inspect the piece periodically and replace any eye that shows looseness

Frequently Asked Questions About Attaching Safety Eyes
Can I remove a safety eye after it's installed?
Not easily. Once the washer is firmly seated on the shank, the eye is essentially permanent. The only way to remove it is to cut the washer off (destroying it) or pry it off with considerable force, which usually damages the shank. Always be sure of placement before clicking the washer in.
What if the eye wobbles slightly after installation?
A small amount of rotation is normal for most safety eyes — the shank is designed to let the eye pivot slightly. What you should not have is significant back-and-forth wobble, which indicates the washer isn't fully seated. Press it down further with a chopstick or return it for replacement.
Do I need to glue the washer as well?
No. In fact, adding glue can interfere with the mechanical locking of the washer and may create a false sense of security. The washer's ridged grip is the correct mechanism. If you feel yours aren't secure enough, switch to metal washers.
Can I use safety eyes on safety-eye-free patterns?
Absolutely. You can adapt any amigurumi pattern to use safety eyes by calculating the right size relative to your finished head and identifying a suitable stitch for placement. Most experienced amigurumi makers prefer safety eyes to embroidery or buttons for their clean, professional appearance.
My safety eye looks slightly sunken — is that normal?
A small amount of sinking is normal, especially in very dense crochet fabric. The shank pulls the front of the eye slightly into the fabric. If the eye looks deeply recessed, you may have used a stitch that's too small or a shank that's too long for your fabric thickness. Try a larger eye or choose a looser stitch point.
Final Thoughts: Mastering Safety Eye Attachment
Attaching safety eyes and safety noses without damaging crochet fabric is genuinely a skill — one that gets faster and more intuitive with every project. The key principles are simple: always insert before closing, separate the stitches rather than piercing yarn, press the washer firmly all the way, and take your time with placement. Follow these steps and your amigurumi will have bright, beautiful, perfectly-positioned eyes for years to come.
