Someone out there, help me make sense of this... I am working on adding trim to the bottom of a cardigan. The trim looks stretchy and ribbed (vertical ribs) in the picture and this would make sense to create shape at the bottom of the piece. This is created by crocheting a row with alternating dc and fpdc then the next row alternating dc and bpdc. This continues and should create the effect of a stretchy rib. Mine does not. I have no idea why but it just looks like lumpy dc, no nice lines. Any ideas what I might be doing wrong? I know this probably isn't enough info for you to diagnose me but I can't get a picture uploaded
