I hate to be the bearer of bad new once again, but that's not very likely. As was probably made rather apparent from that one post, I have never liked selling shirts. Moreover, I have never had any luck with them. I think people may have been able to sense how unenthusiastic I always was about it.
The only shirt of mine I ever really liked was the Snail shirt, because he is my favorite creation ever. I still have quite a few of those left and will probably open a site for it somewhere so I can expend that inventory before moving.
