Before you start you need to understand is that this project is a combination of both origami and geometry. You need to have a plan and your customized plan is ultimately determined by two things: the size of the canned goods you wish to store and the space available in your pantry.
Step 1: List of Materials
Corrugated Cardboard Box ( 48 x 36 )
Ruler (preferably metal)
Pencil (or pen)
Glue (either a hot glue gun or paper glue) or Duct Tape
I used a Large Mirror-pack from a recent move and it had enough cardboard to make three can-organizers. If you don't have one, a typical Large U-haul box is enough to make one.
