That's a sweet DA shirt! I'd totally wear one like that!
I was still wanting to make myself a pair of radish earings to with the t-shirt.
I also have a design made up for a Dumbledore's army t-shirt for DS.
I'm planning on making radish earrings as well. And I got some metallic polymer clay from a swap so's I can make some galleons, sickles and knuts.
Oh, by the way, I think I'm going to join in on the fun! I'm making some Ravenclaw socks right now, from a pattern called Eagle's Flight that I found online. I figured an eagle would be appropriate.
