Okay, I understand how to cast on at the beginning of the row, and I am using a cable cast on to do that. But what does it mean to cast on at the beginning of the next two rows? The row I am casting onto is a knit row.
Do I cast on 3, then knit to the end, then cast on 3 again (which put the extra stitches on the other side) and continue to purl down the row?
If it helps I am knitting from this pattern
