Ok, if patterns are published or posted, and they say that they've been tested, you would expect that they don't have many problems. The pattern I used to make my SP9 partner her birthday present, a circular shawl in a feather and fan lace pattern, really doesn't have a problem in the pattern, but she might have mentioned that it cups! I used a fingering weight cotton yarn on size 5 needles (one bigger than normal cause it's cotton and has no give) and the bleeping thing cups. I soooo don't want to remake this, but I just might have to if I can't block it flat. Maybe it's the cotton, but I hope not.
I'll post pictures after I dye it and block it to within an inch of it's little organic life.
