Heres my blocks.
I haven't done the triangle. I'm still trying to work out the final layout. I tend to let my projects evolve as they go along, which I dont think will work with this. Having looked at the pictures in the software book theres one which sets the blocks on point with spacer blocks between, which I really like. I need to work out how I could do one similar, and how large it would be based on my 4.5" finished blocks, and whether it would need the triangles to make it an appropriate size, and if so what size the triangles would need to be. I think before I get much further I need to spend some time with learning the software.
Anyway, these are the blocks in the meantime.
