When I do setting triangles, you must check the sizes of all you blocks to make sure they will align properly. The only thing I see is the the setting triangles do not look like they are ALL the same size. Did you cut the triangles so that the straight of grain is on the outside edge? Bias edges should always be sewn on the bottom (letting the DSM walking feet keep the bias edge under control) when attaching them to the blocks. I always cut my setting triangles an inch larger because you can always trim them down after the quilt top is quilted. This is the quilt I finished a couple of weeks ago. Will trim it down after the LAQ has quilted it. Hope this helps.
