It is best to insert a stop in the design after the flat part of the embroidery is done and before the raised part of the embroidery is started. Cut a piece of E-Zee 3D Puff Foam large enough to cover the area to be stitched. When the machine stops and is ready for the foam,lay the foam over the area to be stitched inside the hoop. Tape the edges of the foam to hold it down. You may use a spray adhesive as an alternative. Continue stitching the design. Remove the excess foam by tearing away. Tweezers are helpful for the small areas that need to be removed. Use a pointed object to poke in any small pieces of foam that remain and are sticking out of the design. You may also use a heat gun to shrink them into the design. Be careful not to set the temperature too high  to avoid burning the thread.
