1. Cut four pieces of Duct Tape at least 9 inches long. This will wrap around most common cans. Cut two pieces about 4 inches long, and this will make the bottom. The bottom is optional as you really only need side covers, so skip the bottom section if you wish. No bottom, skip to step 4. Place these strips on your wax paper for easy handling.
As you can see, mine sports a fashionable DIY-Shack Logo, and please feel free to do the same to yours :)
These fold flat when your not using them, so put them under your car visor to take along with you. And as with most things duct tape, they are quite durable. You will probably lose it or have it stolen before you wear it out.
