If you can’t laugh at yourself then you are doing something wrong. I have laughed so hard at myself trying to Arm Knit over the last couple of days. I have been knitting for almost twenty years. Trying to get my brain to shift gears from knitting needles to my arm was slightly awkward. I am left handed so I cast on backwards holding my knitting needle in my left hand and my yarn in the right, mirror image to how right handed knitters cast on. I have watched a couple videos on how to arm knit. I have dropped stitches and had my yarn going in the wrong direction a couple of times. The third time was the charm! I finished my Arm Knitting project and it didn't take very long to knit up.
I used a kit from Leisure Arts called Learn to Arm Knit with Instruction Book. I found it very helpful. However, I didn't use the yarn in the kit; I used a bulky acrylic yarn. The first two tries I used just one yarn and it was too thin. On the third time it went better, I decided to double up on the yarn. As I finished, I noticed I should have used three or four strands. I also turned it once before I sewed the ends together to make an infinity cowl.
