OK, so I made this scarf of Red Heart Super Saver, all stockinette stitch, and it rolls up on itself something fierce. I hung it on a peg thinking it might relax after a while, but that's been weeks ago. I soaked it with hot water and hung it to dry, but it curled right back up again.
Any advice how to get it flat? I've heard you can't block acrylic, so I haven't tried the pins approach. Would that work?
