I made them! I made two. The first one was last night. Used size 5 US needles on WW yarn. 4 inch square. It is the first one pictured. It looked a little small. Garter stitch. The second one I made this morning. Used same size needles but with white cotton yarn and 4 1/2 inch square. Made a little more chubber gerbil. I like the length. Needs improvement in the ears. Used a size G crochet hook for the chain. Maybe a different size hook? Any suggestions would be welcome. The cotton yarn seems to hold the shape better,
