Instead of painting graphics on a wall, create a removable version using contact paper or removable wall vinyl. Either material may be layered with additional colors to create multicolored removable wall decals.
Sketch out a design for your decal on craft paper using a pencil. Once pleased with the design, go over the outline with a permanent marker. If you like, use clip art instead and print out the desired image on regular paper. The image on paper must be the same size you intend for your decal.
Cut out the paper decal design using scissors. For tiny detailed areas, make the starting cuts with the tip of a craft knife for better cutting control.
Flip the contact paper or vinyl over so the back shows. Flip the paper template back-side-up onto the back of the contact paper so it will come out forward on the decal. If the design looks the same from the front or back, such as a symmetrical heart shape, there's no need to flip the paper template over. Trace the paper template onto the back of the vinyl using a permanent marker.
Cut the decal shape out carefully using scissors. Use the tip of a craft knife to cut out tiny details when necessary.
Hold the decal up against a clean wall in the desired location. Place a piece of masking tape at the top of the decal to hold it in place temporarily.
Peel the backing paper away from the top part of the decal while the tape is still in place. Flip the decal up temporarily to reach the backing paper. Smooth several inches of the decal down at a time, peeling more backing paper away as you work. Use a plastic gift card or plastic spatula to smooth the decal in place, preventing any ripples and air bubbles.
In some cases, your design idea may involve more than one decal; for instance,
