A few years ago, I did a design project on one of my living room walls. These pictures are from the old house but I'm planning something similar because I liked how it turned out. First, I painted the wall black and then drew a thin, whimsy tree (part of the theme) with a Derwent pastel pencil: chinese white 72B. The frames around the art were handmade. Basically sanded and painted. I had custom glass made from a company that specializes in plate glass. The metal frame holders on the corners were purchased, I spray painted them silver and (struggled to) drilled them through the wood via the back.
