There is a relatively new fusible that is supposed to do the job and not make the fused piece stiff. I can't find it in the clotilde or KQ catalog, must have seen it in Connecting Threads. I caught my attention 'cause it's offered by Marti Michell's daughter's company, Shades. I met Stacy at quilt camp, nice girl.
Love the quilt, hope you had a good time making it.
