Select a pattern for your stencil. A pattern can consist of a design that you created and printed from your computer, a piece of wrapping paper, a drawing or a piece of patterned fabric.
Tape the pattern to a flat surface and layer a blank stencil sheet over it. Tape down the edges of the stencil sheet as well to hold it in place.
Trace the pattern onto the blank stencil sheet, using a felt-tipped marker or a grease pencil.
Remove the stencil sheet and tape it to a piece of plywood or a thick piece of cardboard. This will prevent damage to your table or countertop.
Cut out the pattern on the stencil sheet, using a craft knife. Work slowly, and try to carefully follow the lines you made in Step 3.
Remove the tape when you've finished cutting. Your stencil is now ready to use.
