I’m hoping someone can help me out. It’s my first time knitting arm warmers and, with the help of this site, I learned how to knit in the round. I just finished the right hand of my arm warmer. When my friend tried it on, it fit great but we noticed 2 small holes right at the base of the thumb where I must have not picked up enough stitches. I can’t possibly unravel this. It’s already casted off and done. Is there some other way for me to fix and have it still look good?
