Flipped seams allowances
How do you avoid getting flipped or scrunched seam allowances when sewing rows of blocks together. If you do get "flippies" how do you fix them or do you just let them be.? I've tried pinning, not pinning, glueing, basting, clips, starch, spraying, begging, and swearing, but always seem to get at least one flipped seam.
