This isn't exactly embroidery. It's an easy, unsecured yarn art method, created for kids. You can attach some kind of fusible stabilizer fabric to the underside or get a picture frame for it. You can leave the backside holder section, but remove the glass front so the texture is visible, and it'll hold. If you're really worried, some spray adhesive to the underside of the "embroidered" piece would help to keep the backings/stabilizers in place. 😊
