Ok I think I'm going to answer my own question. The edges of the triangle need to match up with the edge of the hexie...so I think I'm going to have to just cut one, slice it up and measure the edge of the triangle to see if it will match up with one of the dies. I will start with the largest one on the die and see what happens. LOL Gahhhh I'm sick I just don't want to have to think!! LOL
