Start by deciding upon your design. We used masking tape to make the stripes and adhesive hole-reinforcers (for loose-leaf paper) to make the polka dots. The M stencil was created by enlarging the typeface on a photocopy machine and cutting a stencil.
Note: To make a monogram stencil, place the enlarged letter on a piece of Con-Tact paper, which has a sticky back that will adhere to glass. Trace the letter, then cut it out with a utility knife, discarding the letter itself and reserving the template -- remember to reserve the center cutouts of letters with closed shapes, like O and A.
