This is a very simple pattern, and great for beginning knitters who want to get used to working with smaller needles. It’s a good way to use up leftover scraps of sock yarn, or to play around with sock yarn before/instead of knitting a pair of socks. I like using solid-colored cotton if I’ll be adding a face, but you can play around with variegated or self-striping yarns for your pleasure. If you’re feeling even more adventurous, experiment with different gauges and yarn weights and make a condom hat, condom golf club covers, or a gargantuan condom to cover your bird’s cage at night.
