This powder bonding agent is needle-friendly, creating a semi-permanent bond between most fabrics, battings, and textiles! Sprinkle the Quilters Select Free Fuse Powder over the base fabric and lay the second piece of material over the top. Cover your sandwich with parchment paper or another pressing sheet. Then apply heat and pressure with an iron or press (medium temperature) and hold for at least 4 seconds. You've set the bond! You can use Free Fuse Powder to fastening fusible quilt batting, fusible foundations, and fusing fabric to fabric such as appliques, costumes, quilting, home dec, and more!
