For some time now, I had been looking for an inexpensive painting rack or carousel. Yesterday, my wife picked up this kitchen thingee from TJ-Maxx for about $13.00. In turn, it's sitting in a carry tray so it can easily be moved into hiding if we have guests. A multi-tiered carousel was my first choice, or possibly a suitable spice rack - but this one with two side-by-side carousels seems a decent alternative.
UPDATE: My wife suggested I place the coffee mugs with brushes inside the center of the carousels. With the mugs siting in the center, the paint bottles now have a sort of back stop - keeping them from tipping over. As my wife always says, "You need to listen to me." She is usually right 10 out of 10 times.
