I, too, am a geek and sew for Dragon*Con. But apparently for a completely different genre. For this year's Dragon*Con, I will be making myself and a friend two outfits each - one each for Weyrfest, and then anime-specific. I am going to dress up as Howl, from Howl's Moving Castle, and she will be Sophie. Our costumes will be of the first ones you see for each of the characters in the movie. Should be interesting ^_^ For last year's Dragon*Con, I had a Star Wars original character costume that I am STILL perfecting, piece by piece. If I can find my lightsaber over the summer, I will be wearing it again, along with my two new costumes. Yay!
Outside of that, I am actually a costume design major, and recently, I patterned, cut, draped, and sewed a chiton for the lead female choral in my school's version of Lysistrata. I also made a ram head and a sporran for one of the male chorals, and, sadly, I had to fashion a giant stuffed penis. I do believe that particular thing was by far the strangest thing I have had to make for my school. I've done more distressing work (Waiting for Godot and Grapes of Wrath), and I did a couple of pieces for Les Liaisons Dangereuses. Also, three semesters of training have me as now being AWESOME at hand-sewing stitches... so much so, in fact, that I tend to get stuck with jobs that are too delicate for the machines, which gets a little annoying. ^^;
