I have a growing mountain of subscrition boxes that never seem to get used and I find stacking them a pain so started playing around with some to create someting a bit more useable.
All I did was use 2 box lids for each drawer holder section, cut an end of each and sandwiched them together using glue. I did make sure the bottom of the box/drawer fit snuggly into them before glueing them down.
A very simple idea! I am working on another type of storage using Memeboxes.
