Sushi you need to put a Fusible No Show Mesh Stabilizer or iron on interfacing on the back of velvet first. Make sure that the straight of grain of the velvet and the straight of grain of the interfacing are going the opposite of each other This is so the velvet doesn't stretch out of shape. You still have to use the stabilizer for the embroidery. This works for all fabrics that are stretchy. The Fusible No Show Mesh doesn't have any stretch it's a embroider Stabilizer you buy at a quilt/ embroidery machine shop. Hope this helps you.
