I have only made one DWR quilt and I used Eleanor Burns' method of sewing the marked interfacing to a row of fabric strips. You cut them with a 1/8" allowance; turn them inside out, press them and then top stitch them down to your backing. I know this isn't the "real" way to do DWR, however, this worked for me. I did a sample quilt in the 1970s with a DWR square. It was the only one that I didn't finish. So this works for me.[ATTACH=CONFIG]594527[/ATTACH]
