I also built a storage cupboard in wood working room from byfold hollow core doors. It required four 12" wide pair. I'd bought a bunch of them a while ago during a 1/2 off sale, so my shelving unit cost $10.00 to build using scrap for shelf supports. I used 2 small l brackets to secure it to the wall, screwing into studs. I love my stud finder. Now to start using it. It will help keep my room user friendly.
