I use light fusible web for machine applique. It comes with paper back. You trace your pattern on the paper side, trim roughly around it, press the web side onto the back of your fabric, then trim on the pattern lines. Peel off the paper, place it on your background block, then press again. If the piece is large, you can cut out the center of fusible pattern piece before you press it onto the fabric. That way it doesn't get so stiff. I'm sure there must be a tutorial on here on how to do this. It works great!!
