Amigurumi Safety Eyes: Sizing, Placement, and Safety Tips
Safety eyes are the small, shiny plastic eyes with a locking washer backing that give amigurumi characters their expressive look. Getting the size and placement right makes a bigger difference to the finished character than most beginners expect, and using them correctly matters for safety too, especially for anything that might end up in a child's hands.
What Are Safety Eyes, Exactly?
A safety eye consists of two parts: the eye itself, which has a plastic post on the back, and a washer that locks permanently onto that post from the inside of the piece. Once attached correctly, the eye cannot be pulled back out, which is what makes them safer than sewn-on buttons or beads for a toy that might be handled roughly.
Choosing the Right Eye Size
Safety eyes are sized in millimetres, typically ranging from around 6mm for very small characters up to 15mm or more for larger pieces. As a general guideline, smaller characters (under 10cm tall) usually look best with 6mm to 9mm eyes, while medium sized characters (10 to 20cm) often suit 9mm to 12mm. The right size ultimately comes down to proportion, eyes that are too large can make a character look cartoonish in an unintended way, while eyes that are too small can get lost on a bigger piece.
How to Decide on Placement Before Attaching
Unlike most other assembly steps, eye placement is very difficult to undo once the washer is locked on, so this is the one step worth taking extra time on. Use removable stitch markers or pins to test different eye positions first, then step back and look at the piece from a distance, since placement that looks right up close does not always look right from a normal viewing distance. Small adjustments, even a single stitch to the left or right, can noticeably change a character's expression.
How to Attach Safety Eyes Correctly
- Insert the eye post through your chosen spot between stitches, from the outside of the piece
- Reach inside the piece (before stuffing, this is much easier) and push the washer onto the post from the inside
- Press firmly until the washer clicks and locks fully into place, it should not spin or wiggle once secured
- Repeat for the second eye, checking that both are level and symmetrical before moving on
- Stuff the piece after both eyes are securely locked in place
Safety Tips, Especially for Kids' Toys
- Always attach eyes before stuffing, it is much easier to reach the washer from the inside at that stage
- Double check that the washer is fully locked and does not spin freely, a loose washer is the main failure point for safety eyes
- For amigurumi intended for very young children, consider embroidering eyes with yarn instead of using safety eyes, since embroidered features carry no small-part risk at all
- Periodically check well-loved toys for any looseness over time, especially ones that get a lot of handling
What If You Attach an Eye in the Wrong Spot?
Once locked, safety eyes are genuinely difficult to remove without damaging the fabric around them. If you catch the mistake before locking the washer, you can simply reposition it. If it is already locked, the safest fix is usually to carefully snip the post from the back (inside the piece) rather than forcing the washer off, then patch the small hole and try again in a new spot.
Every Yon Crochet kit comes with correctly sized safety eyes matched to that character, so sizing is one less decision you need to make on your first project.
