I made this doggy bunk bed set out of one extra large sized wood pallet and one little half size pallet. I love working with wood pallets because of the rustic look. They are already framed out and built with universally sized pieces so this makes it so easy to use multiple pallets without a lot of cutting and redesigning. The only thing I really dislike about them is the disassembly part of the job. The nails in these pallets tend to be long, rusty and kind of wiry. They are not driven in straight so they tend to be really difficult to pull out of the wood without cracking the boards. Once the unwanted nails and staples are removed, the reconstruction process is easy and actually pretty fun.
