Made from cardboard and paper and painted with acrylic color. It has bowed down a bit in the middle since then, but it's still fine otherwise.
that's a lot of work, fair play! i'm defo bookmarking this for future reference, thank you! 🙌
maybe food colouring or something could be added to the glue to solve the paint problems..? i might try it & if it doesn't work out, a tablecloth will hide all my mistakes, lol
