Finishing Tips for Professional Results
Firm stuffing: Use just enough fiberfill so the piece is firm but not bulky.
Eye safety: For children’s items, embroider eyes instead of using plastic ones.
Seamless finish: Hide yarn ends inside the body with a yarn needle for a clean look.
Premium touch: Add a row of metallic or glitter yarn for decorative details.
These details make your amigurumis look polished and increase their value when sold.
Creative Variations and Selling Ideas
Fridge magnet: Attach a small magnetic disc inside instead of a keychain ring.
Bag charms: Use lobster clasp keychains to easily clip them on backpacks or purses.
Scented amigurumi: Place a drop of essential oil on cotton inside the stuffing for a fresh scent.
For sellers, sets of 3–5 themed sea creatures make excellent gift packs and craft fair bestsellers.
