I am working a Sirdar Pattern (3863). I can work the first three sections until I come to this: BACK With rs facing, rejoin yarn for back and preceed as follows: cast on 1 st, knit to end, cast on 1 st (these two cast on sts to be used for sewing sleeves into armholes).
How do I cast on stitches after I've already begun knitting? It doesn't ask for an increase, but says to cast on.
Someone help me! I'm so confused!
