I found these plans over at Ana White
http://www.ana-white.com/2015/06/free_plans/reclaimed-wood-rolling-shelf, and they ended up being the perfect size for my space, AND they were really easy. Only a few tools are required!
I had Lowe’s cut the 2×8’s so I wouldn’t have to get out the circular saw. I used my Miter saw to cut the 2×4’s. (I woodwork in whatever clothes I’m wearing. I’m a busy mom. You do you.)
