ThinkGeek and Her Universe celebrate the “Year of the Fangirl” with a new Star Trek contest.

“To help celebrate 2013 as the Year of the Fangirl, ThinkGeek has teamed up with Her Universe to host an epic Star Trek shirt design contest, which we’re calling ‘Make It Sew.’ The idea: you send us your Star Trek shirt design, which can be from any of the television series. We go through them and select the most epic one. That person gets a $500 prize and also gets his or her design printed on one of Her Universe’s super-comfy ladies’ blanks and made available here on ThinkGeek for all our Star Trek fangirls.

Prize: $500 (plus, you get to brag that you got your awesome design printed)
Submission Deadline: 11:59pm ET 10/7/13
Winner Announced: 10/14/13″

Entrants can submit up to three designs, original artwork only, and can use all the original television series and the feature films featuring TOS and TNG casts, but explicitly not the movies from 2009 or 2013, as bases for their ideas. Full contest terms and conditions are available on this page.
