I made my own shelves using 1x2 Aspen Boards from the hardware store. They are finished on all 4 sides and typically come in lengths of 4', 6' & 8' and run about $2.50-$6.00 each depending on the length. You can get them in other species too like pine, oak & cedar.

I ran a groove down the center of them using a table saw and built them to fit my space using finishing nails to hold them together and eye bolts and sawtooth picture hangers. They just mount to the wall and use the wall itself as the backing to lean the cards up against. They are very lightweight and sturdy.
