Here is a fun, and interesting, chalkboard cake toy from Craftzine.com. You can find the tutorial here!
This would be awesome in a kitchen, and is perfect for kids to decorate, or yourself. Wouldn't this look awesome in a bakery, with the specials written on it?
It's super easy to make, and uses hat boxes, chalkboard paint, chalk, and glue!
Prepare the work area with a drop sheet or newspapers. If you are taking the speedy route (as I have taken) and are opting to use spray paint, ensure all surroundings are covered and protected from spray. Please remember to ventilate all rooms, if spray painting indoors, and do not expose children to fumes.
Step 1: Place your large hat box on your work surface, bottom facing up. Apply glue to rim of medium hat box and place, centered, on top of large hat box, bottom facing up, pressing firmly. Remove any excess glue with paper towel.
Step 2: Repeat stacking by applying glue to rim of small hat box and placing, centered, on top of medium hat box, bottom facing up, pressing firmly. Remove any excess glue with paper towel.
Step 3: Place a heavy book or weight on top of the stack. Let glue dry and set for at least half an hour.
Step 4: Prop the boxes on a piece of cardboard on cans, or similar. This will act as a rotating stand while you paint. Apply primer. Let dry as per label instructions.
Step 5: Paint the boxes with chalkboard paint. Rotate the cardboard to easily paint all around boxes. Apply two coats of chalkboard paint. Let dry as per label instructions.
Step 6: Break in the chalkboard finish by applying chalk all over the surface and erasing it.
Step 7: If you are using brand new chalk, prevent any scratches on the surface of your chalkboard by rubbing the ends of the chalk on paper first. This will blunt the edges of the chalk and help to preserve the finish of your new toy. Your cake chalkboard is ready to be decorated!
