Are you hand or machine quilting? I work mostly with scrap quilts and have vision problems. Most people don't want to go to the fuss and extra work but with machine quilting I often draw my designs onto parchment paper I get at the dollar store (1x25 feet), sew through the whole thing and then rip out the paper. There's some disadvantages to this, one is that pencil and/or pen may transfer through to white thread and the little shreds of paper go everywhere, but it gives me the finish I want but can't see well enough to do.
