If you or anyone has any questions Dancing Needle just let me know! I think it is easy to make the HSTs this way. I never liked the idea of cutting squares out with a large template and then sewing and cutting again. This eliminates some of those steps and you don't have to buy any aids to make HSTs with. With the open seam method there are no dogears. The HST should come out accurate if you pay attention to your template having the corners on the seam and don't let the template move as you cut.
