I have seen people demo this but with a fusible backing, ironing with a teflon sheet to keep the layers from sticking to the ironing surface. Start by ironing the fusible to the back of your fabric, cut out the pieces, then iron them from the back layer to the front layer on top of the teflon sheet. Let cool and pull the piece off the teflon. It is then ready to iron onto your background fabric all in one piece.
