I'm knitting a Picovoli (two years late, I know!) and have just gotten to the armholes. The pattern suggests doing the "knitted cast-on in purl" for the underarms to make a snug edge. I can't figure out what this is - does anyone know?
I did a knitted cast-on, which was pretty loose, so I want to take it out and try again. I tried purling and guessing how to slip the stitch back onto the needle, but it didn't work -- my working yarn ended up staying at the beginning of the cast-on stitches.
