At work yesterday I scored a huge stack of cards, including a bunch New Yorker cover cards. I am planning on creating a cluster of framed cards on a wall somewhere in the house, because I LOVE New Yorker cover art.
If you find yourself with bare walls, framing cards is a great way to get some art onto a surface without spending much money. You can create a cluster of frames, mix some smaller frames with larger framed art, or fill a small horizontal or vertical space.
In our bathroom, I hung two framed 7 x 7 inch silk screened cards by Tall Cow, one of my favorite card companies. I bought some frames at IKEA and mounted the cards on top of the mat. All together it probably cost me 20 bucks.
