You can make the witches bigger or smaller, without changing the pattern. The witches are about 16.5 inches/ 42 cm high. (In standing position excluding the hat). They are great as Halloween decoration or as a present for a little girl.
The size of the dolls depends on the size of crochet hook, thickness of yarn and how you stuff them; a bigger hook and thicker yarn make a bigger doll. A doll stuffed tightly is bigger than a loose stuffed doll.
