Legacy 100% Cotton Batting is made of 100% Ultra Clean Cotton fibers which provide softness and durability. Quilters and crafters trust and love natural cotton due to the time proven qualities it lends to all projects. Cotton shrinks 3-5% (pre-soak as needed). The lightweight and soft stabilizing scrim binder provides strength and allows for a stitching area of up to 20-25cm apart. If 100% Cotton Batting with no scrim is preferred, stitching area decreases to 10cm.
