I know Kwally's starting a separate thread for this purpose, but in case I miss the deadline I just want to state up front that I'm going in for 3 yards. Also, I'm having trouble finding a place that will make the shirt, and at the risk of sounding greedy, I think I speak for most of us when I say I'd be perfectly willing to pay extra to have it sent as an actual dress shirt. If this is impossible, I still want the fabric.
Edit: after reading other posts by new members, I think it's only fair to admit that yes, I am a newbie. However, I have been trying hard for a very long time to put together a screen-accurate Joker costume, and I'm relieved to finally find a group of people united by the same goal. I can only hope we all find what we're looking for.
