This is a pattern for the Pat and Mat, the title characters of a Czech stop motion animation. Smallish, about 5 inches tall at the end, but size will vary by tension or the size of hook you choose to use. Would say it is medium difficulty and requires a good understanding of crochet to be able to successfully read the pattern.

Outside of standard crochet materials, you will need some wire to make the arms poseable like mine are in the photo.
