There's so many ways to rock the gallery wall, from museum quality cleanness to the funky clipped on art above. You can mix and match your frames or keep it classic...the choices are endless! Personally, I think I'd like to mix and match a bit, but keep it mostly in the same color family. I have two black frames already; one already has art in it, just waiting for me to decide where I to start my collection.
Kim and Scott of Yellow Brick Home just did a great post about how to layout a gallery wall, especially when you're working with limited space. It's all been really inspiring to me, and it makes me want to Buy Art Now! I would really love to have a wall full of prints from artists whose work I admire! I started a pinboard of prints that I would love to buy. There's some (okay, mostly) dorky TV and movie inspired art, but I'm a dorky media inspired kind of person, so I think it works out okay!
Do you have a collection of prints you'd like on your wall? I'd love to see them! Alternately, maybe you're a steadfast original art or bust kind of person -- what's your favorite piece you own?
