Place a cookie sheet or a disposable aluminum cake pan under the screen so that your little cubes of clay will fall straight in. This will help to reduce the sticking together that you are going to get. Push clay patties through screen to make into little cubes. I like to use this rubber sanding block that I got at WalMart. I push down and then slide the block towards me while still pushing down. Doing small sections at a time makes it easy.
