So I decided to make a cover for one of my least favorite books (Heat Transfer) using one of my most favorite cereals (Grape Nuts).
Step 1: Finish your cereal
~Packaging tape or duct tape (clear works best)
~A large (4lb.) box of Grape Nuts or another cereal
Remove the cereal from the box by whatever means you posses.
Break the glue at the seams so you can lay the box out flat.
Position the book on the inside of the box so that you can start to imagine how everything will go together.
Step 2: Mark and measure the spine.
Now, mark the cardboard where the spine of the book touches. Stand the book up on its spine and mark on the back side of the spine.
Then cut the cardboard along these marks until you come just shy of the spine itself. There should be four cuts altogether in order to make two small flaps that we will bend back. Take the book out and tape these flaps down to the inside so they poke out a little from the spine.
Step 3: Crease that cardboard
Use the edge of your table or desk to put a couple creases into the cardboard, right where you marked for the cuts.
Step 4: Add more cardboard for the back cover
Lay the book out flat on the table to find the maximum size you need to make your cover, then add material until it is long enough. Tape it on good 'n solid.
