The materials for this DIY project include wood planter, fast setting cement, outdoor string lights, wood planter, hooks, WD-40, pliers, knife, and 5-gallon buckets. Cover the inside of the buckets with WD-40. Next, pour the cement into the buckets, add the right amount of water and mix thoroughly. Then, insert the tree trunks into the center of the buckets containing the cement mixture. Once the cement sets, remove the buckets and attach small screw hooks into the top of each trunk. Finally, hang the string lights from the hooks.
