Crocheting and finishing flat details
Just like the rest of your toy, the flat pieces start with a magic ring and are crocheted in spiral. Except, after you finish them, you push them flat and don't add any stuffing.
Leaving holes for safety eyes
If you are using tougher yarns like cotton, linen or hemp or plan to use over-sized eyes, it may be worth to think ahead and leave little holes in the fabric for your eyes, nose or joints.
Joining rounds for perfect stripes
Because amigurumi is crocheted in spiral, the end and the beginning of a round do not line up. Which means if you change yarn, there will be a visible step.
One pattern, different yarns
One great thing about crocheting toys is that the exact size is rarely important, which gives you the opportunity to experiment with all kinds of different yarns.
