Ruffle butt (Day 56 KEDfaY)

I finished the edging on the sweater and I now have the opposite problem. Before I ripped it out, it curled under and gave my butt a bubble. It was frustrating so hence why it languished for years. So then I try to fix it and now it's ruffly. I went from a bubble butt to a ruffle butt. Sometimes knitting is very frustrating.
