A recent thread, discussed how to square up from the first cut. One method is tearing, another is the two ruler method. Just out of curiosity (because I'm like that) I first tore both ends of a 1 yard piece, I then had to stretch it diagonally to get the salvages to meet at the corners. I then used the 2 ruler method to get rid of the raggedy edge, left by the tearing, and to my chagrin, when using the two ruler method, I found that, the edge was not straight. It was off by 1/4 inch on one end, and 1/2 inch, on the other end. So which method would you trust?
