have you tried using a ball point needle? sometimes that helps with puckering, although I havent sewn on paper too much, but when I have it seems to really work.
No, Ive actually been meaning to pick up some, I actually am just starting to try doing some 'proper' sewing (AKA actually using the right settings/feet/tensions and needles)
up to this point Ive just been winging it and hoping for the best.
I guess I finally decided to learn a thing or two! hehe.
