Being a purveyor of the stuff of art, I make samples from time to time with materials that we sell so that people can see some possibilities. Product R&D accounts for a good percentage of our sales: to ourselves.

This canvas is linen (lovely bounce) primed with a clear gesso, so that the color of the linen can become part of the scheme in the piece. I chose to do a sketch with oils, putting down only the shadows and highlights so that the tan of the linen would provide midtones:

We also sell tiny canvases/canvaii. These are popular items, but I had to give them a go just for fun. The last picture is of the tiny things on display so you can get a sense of proportion:
