Crown fabric is the hardest to find. Your best bet is to shop around the local fabric stores like walmart, kmart, joanne.... Also, you should ask the other sororities where they go to have their jersey's made. I do know that there is a store not too far from campus that will probably be of a big help to you it's called Greek Unique (I think). The other thing you can try is to go to
http://www.greek101.com they usually have some good stuff too. I'll keep an eye out for you since we both live in the same area and if I find anything, I'll let you know. Oh, by the way,
CONGRATS!
