In this economy I'm always thinking about ways to save, so recently I started saving my "grays".
At the end of a painting session, there's always paint on the palette. But my leftover paints were never of sufficient quantity to warrant mixing them into grays and filling empty tubes. I worried about ending up with lots of tubes that would be filled with small quantities of mystery colors.
But I also hated throwing away perfectly good paint, or worse, trying to use it in the next painting when the colors weren't appropriate.
My solution is this:
- I mix together the remaining paint on the palette and add a few drops of clove oil. Clove oil retards the drying of paint, and smells great. You can also use linseed oil, walnut oil - whatever you prefer. Just don't put in too much oil.
- I then scoop this blob of paint into a plastic food container with a snap on lid. I recently noticed that you can find very small containers in the grocery store. Or you can recycle what you have on hand. Just wash thoroughly first and keep the lids/lips clean.
