I have a few cabinets and lots of drawers to store my hoard. Here are a few photos that give you an idea of how I keep things organized.
These 2 drawers hold the bulk of my Tim Holtz 'Stash'. I keep all the mediums together so I can pick out what I want quickly. I love the organization downloads from the Ranger site that you can use to label all your stains, paints, etc. Makes the colors easy to spot.
