There is a thread on here about whether long armers trim quilts before returning. One thing that is mentioned repeatedly is stay stitching (SS).
I did a quick google search and SS came up regarding sewing but not a lot with quilting. I understand it's a straight line around the edge, but I don't know when it would be used.
So I finish a quilt top, quilt it, trim it, attach the binding with machine, hand finish the binding to the back. At what point would the SS be done? For non-bias edges, do you notice a huge difference with SS? Thank you as always!
