If you're looking for a way to make an accent wall really pop, and if you want to give a room a rustic edge at the same time, a DIY pallet wall might be your jam. First, you're going to need pallets. I've posted links below to great posts that explain where to find pallets, and how to disassemble them into boards. You'll definitely need some power tools and hand tools for this project, including a Sawzall with a 12 inch construction blade (not the five inch blade it comes with) and a power sander. Depending on how you choose to fasten the boards to the wall, you might also need a power drill or a power screwdriver. A laser level helps for mounting the pallets to the wall. Be sure that you have an excellent hammer, as well.
A few words about shipping pallet wood: Pallets can be made from either treated or untreated wood. For interior projects, it is important to use pallets that are untreated, as treated wood can off-gas potentially unhealthy chemicals. Also, beware of nails. Some people like the look of the nail heads that inevitably will be stuck in the pallets, but for children's rooms it is best to remove the nail heads. Pallets are typically splintery, so sanding them down with a power sander is not optional; it's a must. If building a pallet wall is starting to look like too big of an endeavor, it might be a good project to hire a handyman to help with.
