After I snapped a couple pictures I was told that photography wasn't permitted. Is that the case?
A couple years ago, I designed my own "I Voted" sticker on Zazzle. It says <a href="http://www.zazzle.com/stu_spivack/product/217440338930941296" rel="nofollow">"I think I voted."</a> I went to Zazzle today to track it down and searching for "i think i voted" didn't find it. Of course, after I logged in it was easy for me to find but it would have been nice if it were easy for others to find. I changed the title. That may help.
I don't remember where I got the idea. I'm pretty sure I saw it suggested in at least a couple different places. Now there are bumper stickers on Cafe Press. I think my stickers are much better. The font and the background image are appropriately licensed. Just in case anyone was curious. I can't remember where I found the flag picture but it was on some open license stock photography site and the font came with some image editing software. Paint.NET?
