The quilts I make are heavily used and washed often. I have wondered if the "scant" seam would hold together as well as a full 1/4 seam? I haven't used a pattern that has called for the scant seam. I have had to repair some quilt tops that were more like 1/8" seams. Some of the older tops I've repaired have had 1/2" seams. I figure I'll just use the 1/4" as it works well for me.....so far.
