Reversing sewing seams is correct. The most important way to control the bow is to cut strips running the length (up the selvedge) not crosswise and do not cut long strips. Work with lengths that are no more than 18 to 20 inches long. It may seem like more cutting but it is worth it to have straight strips. This is particularly important when you are working with crosscuts of 1/2" and 3/4"
Happy quilting
