I've been trying to think of a good way to organize my oil paints. They were all in a large bin and I was constantly pawing through them and not finding what I was looking for. The other day, at Big Lots, I noticed this plastic 3 drawer unit for about $5. I bought it for organizing my oils.
I have different color groups in different drawers. Top is yellows, sienna, white; middle is oranges, reds, black, browns; bottom is greens, blues, and purples.
It's a simple way of organizing all those pesky tubes of paint and it really works. I'm going to get another one for my acrylic paints.
