Why & When for a Scant 1/4 inch Seam?
I'm wondering the why of the 1/4 inch seam called for with some pattern instructions. Is it for the width of the thread? Is it to have fabric in the block to square up? Less bulk perhaps?
I try for the true 1/4 inch seam and successful most of the time. I want all of that 1/4 inch of fabric in the seam line to avoid skimpy seams. Most piecing is done using the 2.5 stitch length but sometimes the 2.0 length is used too.
Do you use a scant seam?
