I am making a "Wedding Memory Quilt ", from the "Swag Bags" given to the guests for her sons Wedding. The bags are kinda loose weave 100% muslin, so I am backing those blocks. I am also using it for a White based fabric, with Splashes of gold, by backing it with the Interfacing, it makes the Gold-wash Splashes stand out. I like the interfacing and would recommend it.
