[QUOTE=Happy Linda;7118599]The poly will melt if you need to iron. I learned the hard way. Glad it was only on one block.[/QUOTEI
I made a beautiful quilt. I sandwiched it and was quilting it and it all was coming apart. When I checked the seams, the thread was really stiff and scratchy. I continued quilting by stitching very very close to the seam on the side the seams were pressed. what happened was when I ironed the top getting it ready, I melted the thread. It held until I was quilting and it was too late to re stitch the seams. did the best I could.
lesson learned, never again.
