You can do many things with Joss Paper...
Some people fold the paper into boat shape materials for use in other ways, such as putting them together to form larger shapes such as hearts, circles (representing the sun), stars, vases/jars, etc. The paper can come in all sorts of colors, just depending on which you prefer.
