I finally figured it out, it is a complicated way to make different sizes of Dresden plate segments, mostly I want to try to make a pentagram unit....who knows why. So I went figured out all the possible angles and made my own templates from a light weight plastic, put them in a bag with my hand written notes, and then in a drawer where is will probably languish for a few more years.....yes it is crazy but then I am a quilter who buys yards of expensive fabric, cuts it up into little pieces, re sews it back into yards of fabric, spends hours stitching it into a blanket and then mostly gives it away.....now that is a definition of nutso.
