In order for you to follow this pattern’s instructions properly you are expected to have at least a basic knowledge of how to crochet amigurumi.

Techniques you should know are the magic ring, crocheting in spirals, single crochet, half double crochet, double crochet, increases, decreases and basic sewing for attaching pieces together.

If made using medium/worsted weight yarn and corresponding hook size you can expect it to be about 7 inches long. Of course that is also dependent on how tightly/loosely you crochet.
