Using my own artwork, I have created a new Vaquita t-shirt with Custom Ink. Thanks to a comment by Karle from Custom Ink, I have discovered the Campaign feature. It is basically what I thought the Signup Sheet was originally. I have created a campaign, so now anyone in the world can purchase one and get it right to their door. The campaign ends on June 17, 2013 at 11:59 pm, and 100% of profits will go to the Vaquita. Please buy one and tell everyone you know to do the same, so I can reach my goal of 50 shirts sold! Post it on Facebook and Twitter, too! Here is the campaign: https://campaign.customink.com/savethevaquita. Thanks.
