Question on spray basting: When I do a quilt, I cannot finish quilting all in one sitting. When I fold quilt to put away, when I get it back out, it looks like the fabric has shifted and is wrinkled around the fold. Have to reposition. Does that happen to you, or is it just me and what am I doing wrong? I end up spray basting and pinning which sort of defeats the purpose, not to mention cost.
