A few months ago I got a couple of gorgeous art prints from Minted. The first one I created a frameless, floating mount for and hung it in my bedroom. The second print, is massive! (30" x 40") And sat under my bed until I came up with an equally huge frame. There was no way I was going to pay the money for a custom frame, so I decided to make a real, high quality frame myself.
I found a few different tutorials for making a large picture frame, but I wasn't satisfied with any of them. Either they were built too flimsy, required special tools (like a router), or didn't accommodate a sheet of real glass. I'm really happy with the solution I came up with. It was easy to build, sturdy, and is a full fledged frame, with a groove for a heavy sheet of glass.
