What did I do wrong?
I made this red and white sampler with a variety of block patterns. I added the sashing to the diagonal rows, then figured the size of the setting triangles and sewed the rows together. The lower left side in the picture is the first row and the upper right with the maple leaf pattern is the last row added. Why is the last row not the right size? I'm sure it's something obvious I'm just not seeing. The corner triangles haven't been added yet.
