Pictured below is the main office supply drawer in our desk. I used old checkbook boxes & boxes that thank-you notes came in - easy peasy! They're a great size, small enough to group "like with like" (one of the main organizing rules) & easily maneuverable so you can find which configuration best fills your drawer.
And...welcome to my sock drawer! I just have a couple shoe boxes in there, so I can sort between athletic socks, dress/neutral-colored socks, and cute/fun socks.
Just a couple examples!
How have you utilized boxes in drawers in your home? Share some examples!
