When you're in the mood for something quick and tiny...
Supplies:
Yarn: Sample used less than 2g/5yds of Knitpicks Swish in Capri.
Needles: DPNs or circs (magic loop or two circs) to give you a fabric you like with the yarn you're using. Sample used 2.75mm DPNs.
Pattern:
Cast on 8 stitches, join (without twisting) to knit in the round, knit 9 rounds, decrease to 4 stitches, run yarn through stitches to do a purse-string closure, pick up two stitches on the side for a 2 stitch i-cord thumb, work one round, bind off.
Repeat for the other mitten.
Cut a piece of yarn about 8"/20cm, tie it to one mitten, string the other mitten on it, and twist the yarn until it folds back on itself. Tie the ends together, and that's it!
