Hmmm, after I typed Leftover Paint, I thought that might be a good name for many things...
Leftover Paint, the rock band.
Leftover Paint, the art gallery or art store.
Sorry, I got distracted from my post. Anyway... I wanted to paint flowers on fabric. I put a few drops of fluid acrylic paint on my palette and did just that. I had some paint leftover, so I watered it down and painted more fabric.
