Framing prints can be prohibitively expensive. You find something perfect for under $50, but then you go to frame it and end up spending three times that—often more. I'm a huge fan of the San Francisco-based framing site Framed & Matted, which allows you to inexpensively customize your frame and mat online. My friend Rachel DeSchepper recently wrote about her experience for Country Living here.
Another option I'm really digging these days for its simplicity and effectiveness is Chicago-based Well Made's handmade Stiicks collection, which is, quite literally, your art safely sandwiched between incredibly strong magnets. Designer Brandon Knowlden uses four thin strips of hardwood that come from non-forested trees in the Chicago area, and the magnets are mounted below the surface to avoid denting your art.
First you choose from four different sizes and five different finishes.
The pre-drilled top piece mounts to the wall, while the bottom one weighs down whatever you are hanging. Totally straightforward and easy. If you ever want to swap out the print, you simply lift up the top piece.
