I knew I'd seen this somewhere else, and I didn't want to pass off the idea as mine, but I couldn't for the life of me remember whose blog I'd read it on.
Thank goodness for stats.
Someone clicked through to me from a comment I left here at Bella Dia. (Three years ago. How could I possibly have forgotten?) She has some really nice photos on her post, and I suggest you go check them out.
Here's the general idea: Cut off the bottoms or sides of empty brown-board boxes and arrange them to make a drawer organizer. It's easy, it's a good way to recycle, and it helps your stuff go from a jumble to, well, less of a jumble.
I also like to use the boxes from bank checks, but as checks are going by the wayside these days, those little boxes are harder to come by. If you have a lot of small things, like brads or thumbtacks, try using the bottom of an egg carton.
Want your organizer to hang together? Try glue or tape, or just paperclips or staples.
One more use I have found for this idea is to round up those little pairs of socks in my younger kids' dresser drawers. I just cut a larger box a little taller to fit the depth of the drawer. It helps keep everything else folded when small hands aren't rummaging around as much.
