The I used was 4 inches tall, which is a nice depth for the junk drawer because it keeps stuff from migrating from one compartment to another. I used the same system in the silverware drawer, but I cut down the wood to only be about 2.5 inches tall so it would be easier to reach in and grab utensils. We used the table saw for that, but again, a jig saw or something like that would also work fine.
I love how this DIY solution maximizing every inch of the drawer and that I could suit it specifically to our needs. Really, the most time consuming part was loading all the stuff back in and filtering out all of the things that shouldn’t have been in the junk drawer in the first place
So … what’s the state of your junk drawer?
