Place the item on a large piece of strong, but pliable cardboard. Leave two to three inches around the perimeter of your object to allow for a tight, yet firm seal. Make sure you double the size of your object to allow the object to be rolled up.
If you've purchased pre-cut cardboard, two pieces will also suffice. Just make sure the pieces are large enough to accommodate the item, while still allowing the cardboard to wrap around it.
