It bothers me. The first quilt I made was a disappearing 9 patch. I followed all the directions exactly (the 1/4 seam wasn't so exact). When I started to reassemble the 9 patches, lots of the seams wouldn't match. It was too late to change anything. I felt really misled. I'll never make another d9p.
Unless I don't notice it, I'll fix it.
