I made these 2 storage units from chipboard after watching SaCrafters video on YT. They turned out pretty sturdy, though might need some reinforcement between each pad to stop them warping. It was a fun project and they store all 36 of the Distress colours (excluding the seasonal releases).
They are both coloured with Distress Inks and stamped with Tim Holtz stamps.
This is the back of the unit to show the stamping.
