At the first and only National FTE meet that was held in Kansas City back in 2005, we had FTE Tshirts that went up to 6x. I picked up a 5x at the end of the meet and I was swimming in that shirt. lol.
So depending on where you look to get your shirts... My family has a friend who runs an embroidery business, I can run this by her to look at prices.
Guys without a logo essentially all we would be doing is putting screen name and real name on shirt. This would mean that there is only a one off shirt. not much discount to be given. At least with a logo we could get a bulk purchase going maybe and then just embroider names to them.
