I am making a quilt, and setting the blocks on point, so am going to do setting triangles. I already bought the material, and am double and triple checking myself before beginning to cut everything.
I found this site: http://www.quiltville.com/onpointmath.shtml to calculate the size of squares to make, to cut down for triangles. My problem is, doing it this way, I think I come up one inch short (but of course have all kinds of leeway at the side). The 2 squares would have to overlap.
So, I wondered if instead of making a 16 1/2" square, then cutting in into 4 to make the side triangles, if I could make some strip and cut it into 2, so I could get 2 part side by side? Know what I mean?
My pieced block is 22" square, which means the corner triangle is 16 1/2" (rounded up), and the side triangles would be 32 1/2".
So, what would be the size of the half triangles if I did it as the pic on the right shows?
