I've had another experience where the scant quarter inch seam didn't work well. They say if you have the whole thing done the same way, it will be fine, but 'taint necessarily so!
I sewed seven strips together, then was supposed to cut squares out of that. Scant seams made my squares larger so that I could only get two good squares out of the strip. With correct seams, I would have been able to get three.
