Christmas Amigurumi is a collection of great crochet patterns for Christmas. Included are a snowman, santa claus, christmas tree, a christmas doll, trolls and small decorative Christmas figurines for the Christmas tree. You need a basic knowledge of crochet to read the patterns. Sizes: You can make the doll smaller or bigger by using different yarn and hook, without changing the patterns. The small dolls are 1.8 to 2.6 inches (4.5 to 6.5 cm) high. The big dolls are 5 to 8.5 inches (12.5 cm to 21.5 cm) high. The size of the doll depends on the size of the crochet hook, the thickness of yarn and how you stuff it; a bigger hook and thicker yarn make a bigger doll. A doll stuffed tightly is bigger than a loose stuffed doll.
