Whisperlite foundation interfacing is not a fusible. It can be ironed at a medium heat setting, drawn on, stitched through, washed and stamped on. Whisperlite is 42" wide so it's a great value too. Use Whisperlite for string piecing, turned edge appliqué, collage quilting, crazy quilting, foundation piecing and more! Take a look at our YouTube channel for tutorials @ thistledown and company quilts.
