Does anyone remember "stay-stitching" from the days of sewing garments, it's that basting seam that allowed you ease fabric to match darts, etc. I usually have pretty good luck "nesting" seams but I I have a problem I'll slip in a few "stay-stitches" to even things out. BE CAREFUL TO, press - not iron that seam or you may end up distorting the fabric or getting a wobbly block.
