Help Me out Here

Help me out here, Ya'll. Got a few decisions to make lately. Firstly, I have no idea what to do my Final Paper on for Comp. It's nagging at my nonstop. Plus the whole fact that I have to read another full book for Hist 102 and write a paper on THAT that's due in the next few weeks. Lovely time for all, eh?

But here's a problem I'm sure you guys can help out a bit more on - Patches. Ya'll have seen my Denim Jacket every day, but I'd like some help in both info on things and in Deciding. I've picked out a few Back Patches to go on the back of my Jacket, and I just want ya'll's opinions on what one I should use to be the Biggest Patch on my jacket.
