Jeanne S, I went with my original triangle sizes since I'd already cut them, then I sewed the yellow on the other side of the triangle and cut it down to 5" instead of 5.5", so I could get the seam allowance on the point, making the finished height 4.5". It also nicely elongated the blocks, giving longer movement. It meant I had to add an extra row to get size but it worked out fine. Perks of making it up as you go, lol.
