I am knitting a baby blanket from the SnB (Big Bad Baby Blanket). I am at the end where you finish off with 20 rows of seed stitch. I am to start the first row of seed stitch with the wrong side. For the life of me I can't remember what side is the wrong side? Can I use the cast on tail as a reminder. I feel so silly. I just want to finish this blanket! Any help would be appreciated.
