Could somebody please tell me: what is the knitting formula for picking up sts. on the “corners” of a knitted circle to make it into a square? Is it 1/8th of the sts. for each corner? Or what? I read it once lonnnng ago, somewhere, but don’t remember where or what the exact answer was. I am talking about adding on 4 separate small triangles (“cat ears” if you will); I know the decrease ratio, I just don’t know the percentage of sts. to pick up.
