I was having a difficult time laying out a quilt on my design wall. The pattern was 62" x 71" and I was making a queen. I was constantly referring to my conversion figures, running back and forth, and making a lot of mistakes. I finally copied the original four times on my copier, taped the four together at the correct place to make the enlarged version, marked center lines top to bottom and side to side. I then clothespinned the enlarged version to the shade of a tall lamp beside the design wall so I could easily see the finished version as I laid it out. Worked like a charm! :-D
