Colloquium participants bought out our supply of 2012 T-shirts at Salt Lake City, and as the designer, I'm very happy that people liked them!
If we ran out of your size at SLC, or if you'd like to special-order a size that we didn't carry at the event, you're welcome to see my page at apparel dealer printfection.com: http://www.printfection.com/stblogs.
There are several apparel options (standard, women's, ringer-style). In addition to the 2012 Colloquium design (Cathedral of the Madeleine against the Wasatch range):
you can optionally order a two-color design with the Alleluia chant for SS. Peter & Paul, for either the front or back of the shirt.
