I love this display. Just frame the art you have in standard black frames and cut or buy some mats to fit. Custom framing is so expensive. Valk Chuah Art of the Display: Photography by Bjørn/House of Pictures for Skona Hem
Going to have to see if this actually works - Glowing Flower Pots. Paint flower pots with Rustoleum’s “Glow in the Dark” paint. Absorbs sunlight by day & glows at night. Great landscape and gardening idea.
