I had never heard of diagonal backing...always pieced it vertically or horizontally, and had lots of waste. I'm going to look this up. John describes the math but not so much on the cutting and piecing.

Ohhhhhhh wait wait wait. I get it. Once you know how much fabric to start with, you just cut it on the diagonal, then slide the two triangles together until you get the width you need. Then sew the diagonals (okay, you have to be careful of the bias) ... and he says you could even insert a strip of another fabric if you need it even wider (and it's probably more interesting than a vertical or horizontal stripe).

Amazing! Definitely going to try this.

Thanks so much for posting.
