No pins. No basting spray. No safety pins at midnight. Quilters Dream Fusible 80/20 bonds directly to your quilt top and backing with the heat of a warm iron, holding your quilt sandwich firmly in place while you quilt. Same 80% cotton, 20% polyester blend as the regular 80/20 — just with a heat-activated fusible finish. Throw size: 60" x 60". Perfect for quilters who dread the basting process.
