Thanks GramE! I tried one of her patterns and had to print it at 104% to get the little key up to 1". Next time I think I might print at 106 or 107%, because I had to use very scant seams to get my block to come out to the right size. I'm putting together a variety of 12 blocks in kid's prints, for a donation quilt for a child. The Radiating Star would be a good one!
Do your blocks print out at the right size, or is it just my printer?
