(Material used are based on (4) 4 foot shelves, although I only ended up using 3 of the shelves)
Here's how to make the shelves:
Cut boards in half to make (8) 4 foot boards
Apply glue along the edge of one 1x4 board
Clamp 2 1x4's together
Drill about 6 pilot holes
Do the same with the 1x2
Once the glue was dry, I sanded the shelves lightly to get rid of the sharp edges then painted 3 coats of white semi-gloss.
I let everything dry and then it was time for the fun part, installing the shelves! Using the same screws, I marked my studs and attached each shelf with three screws.
My daughter was so excited to pick out which books were going on the shelves.
