If you plan on making more HST or QST you MUST purchase a CD called Triangulations (I have 3.0 there may be a newer version). You can basically print out sheets for any size you are making. You sew on the sewing lines and cut on the cutting lines. Perfect HST and QST every time. It is a fantastic CD and worth purchasing (~$30). Something I will use in quilting for many years. Try it!
