Well, the expensiveness of the project lies in buying the canvas and paint as acrylic painting is not cheap. The rest, the pieces you can find in a repair service as they don't use these anymore. They even have to pay for discarding these as you can't just throw them in the trash. These items need to be recycled, so this is one form of it. Obviously this is just 0.0000000000000000001% of recycling.
