It was surprisingly easy to find enough pallets for our project. We are lucky enough to have a recycle company down the street and after several trips we had all we needed. We laid the pallets in rows and filled them with compost and dirt from our farm (ultimate thrift!).
The worst part of this project was fencing it off from the dogs, horse and rogue goats. We used timbers from cleared trees and field wire. A pallet gate finished it off.
