Easy and cheap (just like your mom). Just kidding (unless your mom is a hobag).
Here's what you do:
1. Go to a thrift store (Goodwill, Salvation Army, whatever weird stuff they have out West)
2. Buy an ugly piece of art with a frame you don't want to set on fire
3. Pop out ugly art (If it's stapled in, just bend back the staples without pulling them out. This is important)
4. If art is matted, turn it around--you will use the back. If it's not matted, you're good to go.
5. Get some chalkboard paint (spray or in a can). Paint several layers of chalkboard paint and let dry.
6. Pop that bitch back in the frame (bend staples back so they hold in your new chalkboard).
7. Prime the chalkboard (this is important, too). To do this, take a piece of chalk and rub it all over the chalkboard. Make sure the whole thing is covered with chalk. Then use an eraser/paper towel to wipe it off.
8. Write, draw, doodle, whatever on your chalkboard. I prefer chalkboard markers.
10. PROFIT! (That's a South Park Underpants Gnomes reference for those of you who don't get it...)
You're done. Do this as many times as you need to fill your home with chalkboards so you sneeze on the dust and look like your hair is white when really it's brown with maybe some grey in there. Or stop when you're ahead and hang it in your office because your soul is slowly being crushed by the bureaucracy at your corporate job and you need something to remind you that you are creative and not a robot. Just me?
I plan on changing out my quote every so often. I had to start with my favorite Henry David Thoreau quote, from Walking. It actually reads, "In short, all good things are wild and free," but I like the abbreviated version.
So make this hotness. All in all, it cost me about $3.00 since I already had the chalkboard paint and chalkboard markers.
