Add the sprinkles to a small dish and put it into the center of the board.
On each side of the center of the board, add 6 cupcakes. Leave a bit of space between the sprinkles and the cupcakes.
Add four Jello cups on the top of the board and four on the bottom, in a line. This will fill the space in between the cupcakes on the left and right, but leave space between the Jello cups and sprinkles located in the middle.
