Okay, so I've always had problems keeping my stitches consistent through my seam allowances. I can reliably get 6-7 sts to the inch in the rest of the quilting, but when I hit the seam allowance (especially if I'm sewing along it), I'm lucky to get 5! What I was wondering was, 1) Would it help if I pressed the seams open so I'm only adding one layer of fabric there, and 2) Would it make much difference elsewhere?
