I will never buy a cutter, as the dies are so expensive, but I did purchase triangulations quite a few yrs. ago and downloaded it to my computer. Bring it up, find the finished size you want, for any sized HST, print off a whole page , put your two different fabrics on the unprinted side, sew on the lines, cut apart and voila, you have perfect HST's. You do have to then take the paper off the back, but if you use a small stitch, it is pretty easy and well worth the effort to have perfect HST's.
