Hey, your frame design is really cool! I really like how you can quickly switch out the print by just opening the sides, but that aspect wasn't clear to me until I saw a video on your website. Also, how do they mount to the wall? And can you explain the deeper version for installing LED's behind them, and do you have any photos of one installed? Good luck, I can see the benefit of these if you have limited wall space and like to change prints around.
