How to Make It
Take a piece of tan foam core, and paint a pink rectangle in the center to mimic frosting. It's OK if the edges aren't straight. Really, you don't want them to be.
Dab brown paint along the edges of the foam board to mimic toasted edges.
While pink paint is drying, liberally sprinkle pink glitter onto the board.
Once pink paint is at least partially dried, spray the section that has been painted pink with adhesive. Toss on rainbow sprinkles until satisfied with the distribution.
Repeat all steps on the second piece of foam core.
Once the paint is fully dried, carefully poke two holes into the top of each piece of foam core with the scissors. Make sure they're relatively close together so the strings don't fall off your shoulders. Pull the yarn through the holes to attach the two pieces of foam core together and make a sandwich board.
Wear proudly to your Halloween party—but stay away from toasters.
