Making your own drawer dividers doesn't have to be complicated or expensive.  And you don't have to use bulky wood or commit with nails and glue.  In this tutorial, I'll show you how to build your own drawer dividers for about $5 (for the drawer shown).  It's easy, fast, and I'd say foolproof!

1. The Hardware

Aluminum C-Channel is available at all the hardware stores in different lengths.  It's inexpensive, about 10 cents per inch - so per divider, you are looking at right at 50 cents in c-channel (I round up to 60 when counting screws).  It's also easy to cut with a jigsaw and a metal blade, since aluminum is such a soft metal.  I am using this 1/2" C-Channel.

Per divider, cut two pieces of C-Channel slightly less than the overall height of your drawer dividers, using a jigsaw with a metal blade.  Make sure the C-Channel is well clamped and wear safety glasses and hearing protection.  

Then drill two holes in each cut piece with a multipurpose or metal drill bit.  The holes should be just slightly smaller than your screw heads.

Attach the C-Channel pieces to the inside of your drawer using 1/2" wood screws (similar to ones you might use for attaching hinges on a cabinet). I used screws like these.

You'll need two per divider, on each side.

The Wood Dividers

For the dividers, I used (and recommend) 1/2" thick hobby boards.  I choose a 2-1/2" width for this drawer, but you can use other widths.  Just make sure you don't create a super tight cavity that is hard to reach into.

Simply measure in between your c-channel pieces, subtract a little to allow for the screws, and cut the wood piece to fit.

The wood piece will slide into the c-channels and stay secure.

You can also add dividers to dividers (as shown below) in the same method.

This gives you infinite possibilities to customize your drawers with dividers.
