This idea is a simple way to make a fingerless glove that fits well. Working in the back loops creates a stretchy fabric and eliminates the need to add or subtract stitches for shaping.
I used worsted weight yarn and a 'H' hook. Make a chain as long as you want your glove measuring from the top of the palm. Crochet in back loop until the glove fits snugly around your wrist and loosely around your palm. Join into a tube leaving a hole for your thumb about 1.5 inches from the top.
You can leave the thumb as it is or sculpt a thumb cover. That's the tricky part. I will write this up later.
