Is it a sock? Is it fingerless mitts? Until you get to the heel turn, it can be either. A tube is a tube is a tube until you put a thumb gusset in it, right?
Fingerless mitts and socks have so much in common. Have you ever noticed that the cuff of most socks fits your forearm like a glove? A standard 56/64/72-stitch cast-on often works as well for a wrist as it does for an ankle. Add a little ribbing to help with the fit, drop in a thumb, and BAM! Fingerless mitts.
These mitts are ribbed at the sides for fit and ease. Each mitt has a flat stockinette panel on the top and the bottom. Think of the flat panel as your canvas. Keep it plain to highlight a busy yarn or add some decorative embroidery to truly make these mitts your own.
