Building cardboard flat files

—News from the studio—

A pile of my prints.

Often, when I find a need for some resource in the studio, I will build it myself. This week, while in the process of organizing and documenting all my artwork, I found that I needed some flat files to separate and store my prints, drawings, and small paintings. Here's the story of how I found a cheap solution.

I began with a bunch of free boxes. I cut them in half and shortened the width of the side flaps so I could reassemble them only as deep as a strip of 1x2. This meant that the front and back flaps also had to be cut down to the same size.

For the 1x2 strips, I found eight foot sticks made of recycled wood fiber for $2.24 each. They come coated with white primer, so they were a perfect choice. I cut two pieces from each stick for the sides of the flat file and stapled the cardboard to the wood. Now, I had two parts for the flat file: a top and a bottom.

Stapling the cardboard sides to the wood

I stacked the top and bottom pieces and stapled the loose cardboard to the tops of the 1x2s on each side, leaving the staples off about 1/3 of the length from the top so I could make a larger top flap. I only had to staple down one half of the top and bottom since the cardboard wraps around and is stapled on the sides. To make the flap, I very, very lightly scored across the top with a utility blade. When making boxes, I always score the side that bends in.

I taped the flaps down in the back; they never need to be opened.

The back flaps are permanently taped.
The front ones can be taped closed with less tape as needed.

And here are my six finished flat files. I've already got one in use. They are light, sturdy, and easy to stack. And they each cost me only $2.24 in materials.
