Barb, if you get a chance check out the book "Stars by Magic" by Nancy Johnson-Srebro. You don't work with triangles, just sew squares and rectangles and cut the diagonals later.
I just read about that last night as I studied my next top--pattern by this creative woman from a book called
Big Block Magic. It's called Tree of Life--and the diamonds will be from rectangles. Thank goodness. :lol: I have the material picked out and I'm headed in to start cutting.
