Now that you've got a screen you are ready to print.
1. Mask the edges. The main weakness of these home screens is the edges. It's a good idea to put some masking tape along the edges of the screen before you start printing so you don't get any sloppy leaks off the sides.
2. Place your fabric on some papers to protect the surface underneath. If you're doing a t-shirt, put a piece of paper inside the shirt.
3. Put the screen down on your fabric, put some printing ink along the top of the screen, and pull it over the image with your art squeegie. If you can't afford a squeegie, use a piece of cardboard.
Be very careful not to let the screen move while you are printing. Hold it down firmly. You absolutely have to print on a good flat surface or you will get terrible results.
4. Lift the screen and admire your work. You rule!
