Anytime I have a pattern that needs inlarged I take it to the local mom and pop shop copy place, she can do HUGE pieces and only charges me about 50 or 75 CENTS to do a copy that is...well to say the least HUGE!
and the great thing is there is never a wait to get something done. I don't have to wait in a line to get it copied, or a line to check out. Checky out if there is a local shop!
