I don't know if it's the same stuff, but I used to use fusible web, for garment sewing (facings, etc.). Worked great, until the item had been washed/dried several times. Eventually, it would separate from the fabric and end up as a sort of "web" hanging from the seam line. That was years ago . . . but I would try it on a sample and wash/dry it several times, before using it on a frequently washed/dried quilt.
