Step 1

Pick your pallets. All pallets are not created equal. They come in many sizes, and can be made from fir, pine, oak, poplar, or some other type of wood. The pallets you choose don't have to be in perfect shape, but they shouldn't be missing boards. For the purpose of building a foundation, the most important characteristic is thickness—all the pallets you choose for the project should be uniform in this regard. If you get all your pallets from a single source, such as a garden center or a furniture distributor, you'll have a better chance of finding ones that match than if you get them from different sources.
