I enjoy creating painted papers for my Mixed Media collages. When I work small I use already mixed paint and squirt onto a plastic palette which in my case is the discarded plastic tops of carry out salad containers. I use therse "palettes" over and over as acrylic paint dries from one use to another. When the palettes get so caked with paint that they begin to peel...I throw them out. Reminder, always keep your food products far away from your art products.
