Pfaff Metal Hoop 180x130mmHoop Projects Without Damaging Your FabricSome fabrics are more difficult to hoop than others or should not be hooped at all, since hooping can damage the fabric. Thick and course fabrics can be difficult to hoop as well as thin and glossy fabrics. Hooping ready to wear garments can also be difficult due to seams, narrow areas or buttons/rivets. Embroidering difficult fabrics or garments will no longer be a problem with the creative™ Metal Hoop!
