I made a very simple corner display to use as a background for photos. It's basically three MDF-boards glued together to form a corner, then wooden planks added and painted. (The planks are from a hobby store - actually these are scraps from when I worked on my dolls house, the MDF boards I had lying around and the paint was leftover as well! Super cheap display corner!)
R. asked me about it - here are some photos!
