Crochet mini doll pattern
Create a mini doll. This is a fairly quick project (depending on the amount of detail you want to add). You should have some crochet experience, preferably some experience with amigurumis.

This project is perfect for left over yarn, as you just need a tiny amount of each color. I prefer cotton yarn tho. Adjust your hook size to be suitable for the yarn you use (make sure to use a hook on the lower range of the recommended size for your yarn)

Enjoy!
