Scissors or a craft knife
First you need to measure the depth of your desk drawers. My drawers were about 4 inches deep, so I made sure that the boxes would fit.
Take your box and cut the front off. If your box is deeper then your desk then simply cut into the sides, as to make the box shallower.
Now you should be left with a box looking something like this. Now, take your stapler and staple the flap up (Hot glue would work too, I just didn't want to get my glue gun out).
Since no one likes the look of cardboard boxes, I got out some pretty scrapbook paper and decoupaged it on. For those unfamiliar with decoupage, you simply put a layer ofmod podge (or other decoupage glue) where you want the paper to go, stick the paper on, then put another layer of glue over the paper. Pretty simple!
This tutorial is super easy! Try it. :D I plan on making more soon.
