Tips for a Neat Finish
Use Tight Stitches
Tight stitches help the koi fish keep its shape and prevent stuffing from showing through the fabric.
If your stitches look loose, try using:
- a smaller crochet hook
- tighter yarn tension
- cotton yarn instead of soft acrylic yarn
Keep the Fish Lightly Stuffed
Do not overstuff the fish.
A softer body helps the koi fish:
- keep a smoother shape
- look more natural
- feel lighter as a keychain
Gently shape the body with your hands while stuffing.
Keep Fish Scale Rows Even
The BLO scale texture looks best when:
- stitch spacing stays even
- yarn tension remains consistent
- scale rows are slightly offset
This creates the layered koi fish effect more cleanly.
Secure the Keychain Ring Well
If you plan to use this crochet fish daily:
- sew the top area securely
- reinforce the keychain loop
- weave in yarn tails carefully
This helps the small crochet keychain last longer.
