Casting on new stitches after a moss/seed pattern row
I have a pattern for baby booties that requires me to finish a row using the moss/seed pattern, and then "cast on 8 stitches" at the end of that same row. It doesn't say to m1, just cast on.
Does that mean I use a second piece of wool to cast on these new stitches? Or is there a way to use the wool attached to my knitting to keep casting on?
I can't find instructions on this technique anywhere, but am familiar with casting on.
