Cut a piece of cloth in a square 7 inches across by 7 inches wide.
Fold the cloth over to create a rectangle. If you need more cushioning than this provides, you can insert a thin piece of foam between the cloth.
Place the cloth on the underside of the violin between the chin rest and the right-hand side of the violin. Secure the cloth with a rubber band from the button of the violin, located on the chin rest, to the left edge of the violin.
Create a more secure violin neck rest by folding the fabric over and sewing with a thread and needle along the edges of the cloth. Include your foam padding if you want a thicker neck rest.
