Open up your creative mind and let it flow! The easiest design for a bandsaw box is one that allows for the fewest cuts. If you could make one continuous cut around the box, that would be great, but do what your design calls for. If you want square corners, you may need to use another tool like a miter saw to trim the ends of the block. For this example, I chose a heart shaped design.
Draw the outline of the box on the front of the block.
