One hand warmer took 1.3 ounces. I bound off with what the designer says is the right side on the inside. I did not like the bar across the base of the picot showing on the right side.

Love the pattern and the yarn. These will be gifts for at least 3 people on my gift list. Next pair will use some Scottish yarn. One ball is an odd dye lot. So to make the pair work with 3 25 gm balls, I am casting on only 43 stitches. If I ever use worsted weight yarn, I would use larger needles and less picots on the thumb opening.
