Hi Nancy... Had to comment! I use the "ubiquitious plastic box with the blue lid" both in the studio and out. I have the plastic supply store cut a heavy acrylic plastic panel to exactly 12" x 16". (About $7) I put a piece of brown paper bag cut to the same size under the plastic. I use a dab of silicone sealant at the corners of the plastic. (a small tube is about $3) (Originally, I used glass for many years, but recently broke it on a trip to the ocean and had to fake it for the rest of the trip. No more glass!) It works perfectly. I can turn the box upside down, sideways, it doesn't matter. When I open the blue lid, I'm ready to paint! Keep Painting! Bruce
