CUTTING OUT YOUR STENCIL
Place your plastic over your design. Tape the design to the plastic. Make sure your craft knife has a nice sharp cutting blade. Trace around the lines of your design carefully with your craft knife. Use a ruler to keep your lines perfectly straight.
MAKING A STENCIL WITH A REPEATING DESIGN
When making a stencil with a repeating pattern, registration marks will make your stenciling project easier. Once you have traced one complete stencil design onto your plastic, move your paper pattern to where the next repeat of the design would begin.
Trace a few of the stencil elements onto your plastic and cut them out. When you are stenciling, you can line these up with the previous section you have stenciled to keep everything evenly spaced and straight.
