They knit up really fast - a one day project for me. I adapted a mitten pattern to make these cozy little hand warmers. Adjusting the basic mitten pattern was done by adding a couple of thumb stitches and binding off before the thumb and hand decreases.
Cast on 28 stitches. Divide stitches onto 3 dp needles or 2 circular needles. Join for working in the round.
Knit 16 rounds
On the next round, K1, place marker, M1, K1, M1, place marker, knit to the end of the round (increase 2 stitches).
Knit 2 rounds
* K1, slip marker, M1, knit to next marker, M1, slip marker, knit to end of round.
Knit 2 rounds *
Repeat from * to * two more times until you have 36 stitches total and 9 stitches between your markers for the thumb.
K1, remove 1st marker, place 9 thumb stitches on a stitch holder, remove 2nd marker, cast on 1 stich, knit to the end. (28 stitches)
Knit about 14 rounds, ending at the length desired. If you like the rolled look, make sure the length allows for the roll. Bind off loosely.
Arrange the 9 thumb stitches on 2 dp needles or 2 circular needles and join with RS facing to beginning of first needle. Using a 3rd dp needle or one of your circular needles, pick up and knit 4 stitches in the thumb gap. (13 stitches). Join for working in the round. Knit about 8 rounds, ending at the length desired. Bind off loosely.
