There's lots of different methods to doing typography on chalkboards of all different sizes, but for a large scale project, my favorite way is using an overhead projector.
Yes, like the old school ones. I bought this projector from Goodwill for $15, and later I found transparencies (the clear papers) from a yard sale for next to nothing. I bet you could borrow one from a school, your church, or put a request on facebook to your friends. You might even be able to purchase one from craigslist.
So to begin, you'll need an overhead, transparencies, a chalkboard, chalk (& chalk markers), and a quote you like. I made this one, so if you don't have one to use, feel free to snag this one.
All you need to do is print the image onto the transparency. I worried that because my printer is inkjet not laser, that it wouldn't work, but it actually does- just don't touch the image because the ink is really just sitting on top of the paper.
Carefully position it on the overhead where you want it to shine. I think getting the placement right can take longest, sometimes. Move the projector/transparency/focus knob up & down, forward & back til you get what you want.
Then begin tracing- and while you do that- you realize you've spelled "loveliest" wrong, and you have to go back and fix it later. Dang!
Whatevs. I keep pressing on. I like to use the chalk pen for my rough draft and then go over it all with a piece of chalk when I'm done. You can erase with a paintbrush or q-tip dipped in water. Works like a charm.
Take a step back, take a couple pictures, and enjoy your new artwork! I did this during naptime, so the whole project, including designing the art took me 2 hours. Not bad, right?
I really wish cooler weather would get a hint from the fall décor I keep adding to my house.
It is still so hot!
