I need some help. the box I bought to transport it in is slightly too big and has no insert to hold it in place. I was going to put the cupcake on a board but how can I stop it from moving inside the box?
The board has to be the same size as the box.
Drive a skewer/sharpened dowel through the cupcake into the bottom board.
Put a piece of shelf liner (non skid pad) under the board.
