Nanci, you make a good point about the fabric. I've seen some simple but nice t-shirts made from a cool technical fabric, but not sure of the difference in cost between that and cotton tees. Also, may I suggest a v-neck vs. traditional round neckline--cooler (heat-wise) and cooler (appearance-wise). A graphic would be great, if someone here could do something original--otherwise we might run into copyright issues.
