I saw some blocks like this on another craft blog (can't remember which) that was actually about something else. They just happened to be in the picture and I thought to myself, "I could make those." My sister (Thanks Megan!) cut out the letters for me and supplied the blocks. I spray-painted them black (using the new Martha Stewart spray paint stuff - totally awesome!) then gave 'em a coat of slime green, just for good measure.

After that, I put the letters on the paper and mod-podged the heck out of those suckers. What do you think?
