Monoprinting with aluminum foil and plastic bags

I made these two videos to demonstrate how to make monoprints using washable markers and materials that you can easily find at home: aluminum foil, sandwich bags, plastic shopping bags. I am thinking that the plate (the surface prepared to be inked to make prints) for this project could be made with any waterproof material. I made the second video after realizing that maybe not everybody has a spray bottle at home.
