Make your own monster! This is a NO SEW pattern!
Gauge is not important for this project. Use whatever hook size will produce stitches tight enough that the stuffing does not show through.
I used Bernat Baby yarn in superfine “Antique White” and a size D/3.25mm hook. This used 0.5 ounces of the yarn and produced a Jimothy that was about 4 inches tall.
Make a bigger Jimothy using larger yarn, or go mini by using sock yarn or crochet thread.
