Oh gosh, I'm sure glad I asked questions!! Thanks Feathers. I would have done it all wrong. For some reason I was reading that as a "9" and thought you cut that as a rectangle at 9x9 3/4 and then cut it on the diagonal. No, I will make a template the size that you say it is and use that! I'm sure that would be best. My math ain't so great! LOL I'd never be able to figure that out with a rectangle. :lol:
How did your friend put this together?...just block to block, or did she use a sashing inbetween? It might be interesting to put the blocks right next to each other and have an alternate look with the two triangles coming together. I'll have to make a couple of mock blocks and play with it. Thanks for all your help.
