Pallets have always been a perfect material for any types of crafts, especially if you going to make something rustic or industrial. These garden beds are made of wood sourced from pallets, painted and attached to casters – such a great idea! Just take some wooden boards (if you don’t have pallets, just take any that you have); cut them to the size you want. Now attach them to each other forming a box, better use nails to make the bed more durable. Stain or paint the boxes as you like and let them dry. Now attach some steel wheel swivel casters of the appropriate size and voila!
