Step 1: Roll out base clay
Roll out a small package of polymer clay to ⅛ in. / 3 mm. thickness. The clay should be about the same size as your light switch cover. This will be the base clay that you’ll adhere your clay cane slices to.
Step 2: Leave an impression of your light switch cover
Set your light switch cover over the top of your base clay. Press down firmly, so that you leave an impression of the shape on your clay. Carefully remove light switch cover.
Step 3: Slice your polymer clay canes
Use a clay blade to slice your polymer clay canes in an even, downward motion. Your clay slices should be about 1 mm. thick.
Place your clay slices on top of your base clay, starting from the center. Use whatever design you prefer; don’t be afraid to mix and match. The more clay slices you add from different polymer clay canes, the more original your look. Tip: Avoid positioning your favorite clay slices in the middle of your base clay – you're going to cut that area out later to accommodate your light switch.
Step 5: Roll out your design to an even thickness
Use a clay roller to roll out your design to an even thickness. This will bond the clay slices to each other, and to your base clay. Tip: If the clay sticks to your work surface, gently remove with your clay blade.
Step 6: Place clay design onto light switch cover
Place your flattened clay design onto your light switch cover. Gently press into place, so the design is centered.
Step 7: Cut out a hole for your light switch
Use your index finger to find the switch hole in your light switch cover. Cut it out with a utility knife.
Step 8: Trim around the edges
Use your utility knife to trim around the edges of your light switch. Leave a small border slightly larger than the light switch cover so you can tuck the clay neatly around the back.
Step 9: Attach screws
Use your index finger to find the screw holes in your light switch cover. Punch screws through clay, being sure to press them all the way through.
Step 10: Fold edges around the light switch cover
Flip your light switch cover over. Gently pull the edges of clay towards the back, so they’re tucked around neatly. Use your utility blade to trim as needed.
Step 11: Bake
Bake your light switch cover according to the directions on your polymer clay packaging.
All done! Now you can install your colorful new light switch cover to the wall. Nice job!
