I am knitting a Lion Brand pattern, Cuddle Bunny pattern #60635....I need to cast on MORE stitches after already knitting 28 rows...I have no idea how to do this, as I am a pretty new knitter. I assume it means to cast on my already knitted portion not on a new needle?? Or do I cast onto my empty right hand needle and ADD it to what I have already knitted????? Very confused.....any answers would be greatly appreciated! Thank you!
