Cut Aways are stable, soft stabilizers that remain under the fabric permanently. A Cut Away non-woven prevents the fabric from shifting while embroidering.
It is called Cut Away because you simply cut away the overlapping remains of the stabilizer with scissors.
Cut Away non-woven is ideally suited for large, elaborate embroidery with high stitch count and high stitch density. It is also well suited for embroidery on thick, expandable textiles.
