The LeMoyne Star is an old traditional block - I've seen versions from the early 1800's! It is a beautiful block, but a little tricky with those Y-seams, though. I wanted to show you how I do them by machine. First you cut all your pieces. I used EQ7 to print out my template for the diamond and rotary cutting instructions for the background pieces. The best thing about using the rotary cutting instructions is that it figures it out so the triangles are cut with the straight of grain on the outside of the triangles, making it much easier to get a block that stays square!
