I'm working on my first quilt top that is all 60 degree triangles, the previous ones have been mostly rectangles/squares/HST with no bias edges. Of course I didn't sew a few rows right and need to rip out the seams. I've tried ripping out the seams as gently as possible but still feel I am getting some stretch at the corners that are mostly bias. Any suggestions on the best way to rip out these stitches and keep my remaining triangles unstretched?
Painters tape as close to the seam as you can manage helps!
