Yes, it is possible to build a sandbox in your backyard using a tarp. You will need some plywood, screws, and nails. Start by cutting the plywood into two equal pieces that are each slightly larger than the area you want your sandbox to be. Next, attach the two pieces together with the screws and nails. Make sure to secure them tightly so they don't move around when you're playing in the sandbox. Finally, cover the entire frame with the tarp, making sure it's securely attached at all four corners.
