My sketch is a bit wonky but it should work. You may prefer to cut to the 1/4" instead of 1/8", gives you a tad more to plat with. I would begin sewing from the bottom end of the triangle for the first seam
If this is too small the upright line is 6 1/8" and the bottom is 4 1/8"
Hop it works for you
