I found a great replacement for a traditional palette for acrylics, and perhaps even oils (although I'm not so sure oils would clean up as nicely).
I sit on a stool to paint, and I don't like having to hold a palette in one hand while I paint. When I purchased my art supplies, I bought a palette that had six little wells, and I hated it. It didn't give any room for mixing colors. I used it once and trashed it.
In a pinch, I used an old table that had been rattling around the house. At walmart you can buy these cheap little three-legged 28" round particle board tables with a glass top, and sometimes they come with a long skirt to go over them. They're very inexpensive. I took the skirt off the table and left the glass sitting on top of the particle board.
This serves as a perfect palette, at least for acrylics. Plenty of room to mix paint, just at the right height, and VERY easy to clean off -- simply let the paints dry for a couple hours, then run a bit of warm water over the surface and the paint peels off easily. Being glass, it also doesn't add to the already-fast drying time of acrylic paints like paper palettes do, and it comes clean EVERY time. You can put a piece of paper under it to achieve a white background.
I'm lazy sometimes and leave the paint on it overnight, and then flip it the next day and use the other side. LOL
But anyway, those of you who are frustrated with your palette's size, try this one.
Life is less about who you are, and more about who you choose to be.
