The instructions show four different ways of sewing the HST. Method 1 - Create eight half -carré triangles from a set of squares. Method 2 - Cut set of triangles ready to sew from bands. Method 3 - Mark and sew 1/4 thumb seam lines. Method 4 - Cut the updated HST to the right size. Choose the method that suits you best. The rule easily slides on the fabric until pressure is applied. Then, our exclusive coating keeps the fabric in place during the cut, eliminating the shifts and the missed cuts!
