The water pots have a clip attached to the back! I found them on Amazon. The caps don't screw on the best, but they work well enough. If they didn't clip on, I would probably use magnetic tape like I do with the paint palette. I'm glad my post organization was useful! Let me know if you have any other questions and I'll be glad to share more photos or links.
