Thimblebug, I was hoping to make this in a 10 inch block and used My Design wizard and the block came out like crap. I then pulled out the orginal pattern and tried a block with that and again crap. I was hoping there was a simple math formula I use. I am hoping for something between a 10-12 inch block.
Mad quilter - if you have a formula I would be glad to takel it.
I think I am just going to start and chain sew it making sure all the blocks match before adding the next layer. If I make the squares for the triangles larger then they need to be I should be able to trim them to match. I think I will start fresh in the morning.
