I cut wood from pallets that were donated to the school from a Girl Scout troop in Suffolk. The wood was painted blue, then I used paint markers to write the rules as well as things people can learn from working in the garden. We covered them in a layer of Modge Podge and then sprayed them so they wold be waterproof. The wood was then nailed to 2 X 4 with the help of my friend, mom, and dad. These will be put in the ground in POLA shortly.
