Amigurumi is the Japanese art of knitting or crocheting small, stuffed yarn creatures. The word is a compound of the Japanese words 編み ami, meaning "crocheted or knitted", and 包み kurumi, literally "wrapping", as in 縫い包み nuigurumi " stuffed doll". Amigurumi vary in size and there are no restrictions about size or look. Wikipedia
