I started a new job recently and my hands kept getting cold in the office. I thought, "I can do something about that!" I didn't want anything that required knitting fingers or thumbs, so this pattern only includes a thumb hole. After knitting the first one with ribbing at each end and stockinette for the rest, I decided I wanted the second one to be a bit more snug. So the second one is entirely ribbing. It's your choice as to whether you want stockinette or ribbing - or you could do one of each, too!
I used Malabrigo Finito (120 Lotus colorway) and 3.5mm dpns. One skein of Finito is 185m and I didn't quite use the full skein. Obviously, the amount of yarn needed will be affected by how big around and how long you choose to make the warmers.
c/o 64 sts. (20 sts, 24 sts, 20 sts across 3 dpns)
Knit 1 foundation row (you could go straight to the ribbing, but I always prefer a foundation row)
R 1 - 10: K2, P2
R 11 - 55: K in the round (if you choose to make the warmers entirely in ribbing, then the ribbing will continue in this section)
R 56 - 65: Knit (or rib) flat on dpns to create the thumb hole
Rejoin in the round
R 66 - 67: Knit (or rib) in the round
R 68 - 69: I chose to decrease a few stitches, which is optional. For the knit only warmer, I K2tog at the beginning and end of the 2nd dpn on round 68 and 69. For the ribbed warmer, I K2, P2 for 24 stitches so that was into the 2nd dpn, then K2tog and P2tog, and continued in rib for the rest of round 68. Round 69, I K2, P2 for 23 stitches, then P2tog and K2tog to incorporate the 2 decreased stitches from the previous round into the pattern. Either way, you should have 60 total stitches after these two rounds. You can also decrease a few more if you prefer.
R 70 - 72: Knit (or rib) in the round
R 73 - 78: K2, P2
Knit 1 ending foundation row
Bind off in your preferred method
