I have been experimenting with used eye glasses cleaning wipes to be used as canvas. I smoothed them out while still damp, then ironed the remaining creases out. Sorry, no pictures yet, but the wipe has a canvas sort of texture and would have been thrown away anyhoo. I figure some diluted PVA glue would give it some body to hold a shape.

What about the cloth thickness? The one I have is pretty thick.
