I'm very fussy when it comes to shirts, and always end up with 100% cotton, so the rolling method never seems to work for me. I fold them shop-style, that seems to put the creases in inobtrusive places. Basically, do up a couple of buttons, turn over, fold the body in on both sides so there are two flaps meeting in the middle. Fold round the sleeves so they meet the flaps, then fold in half. Then I store with others inside a plastic bag, or fold in half again if it is packed alone.
YMMV, but this works just fine for me.
