Crocheted Luke snow suit and Tauntaun by the very talented Mara Saxer aka @mausmara.

It is time.

Timmy has been re-arranging the costumes in his cosplay trunk. We know what this means. San Diego Comic-Con is coming and we need stitchers, knitters, crochet hookers, hot gluers, haberdashers, and crafty-makers for Timmy's Volunteer Costume Corps!

We started this project two years ago and we still cannot adequately thank the volunteers that have made Timmy's current extensive collection possible. Each and every costume we've received has elicited squees of delight (video proof of the squees) and they've served us extremely well over the years. With your costumes, Timmy has traveled the world as an ambassador of geekery. He's met the shiniest people and probably flung poo in places that we will never see with our own eyes.

Do you have the time and skillz to take Timmy's cosplay collection from the trunk to the wardrobe? Scroll down for our costume wish list, take a look at his existing collection on Flickr, and sign up below to volunteer!

Our deepest costume wishes, with the already taken suggestions struck through:

This...might not end well.

• Alien, Big Chap, or the Alien Queen (already have a chestburster and a tiny facehugger)
• Diablo or Tyrael
• Classic Spiderman
• Rick Grimes from the Walking Dead (we already have a zombie Timmy)
• Dovahkin, with horned helm (no Lydia, please)
• Katniss, Peeta, Effie Trinket, Haymitch or Gale from the Hunger Games
• Batman, Bane or Catwoman (sure, why not)
• Your favorite (or least favorite?) Game of Thrones character (Tyrion Lannister, Cersei Lannister, Jaime Lannister, Daenerys Targaryen, Viserys Targaryen, Eddard Stark, etc)
• Abe Lincoln: Vampire Hunter
• The 10th Doctor with his distinctive trench, sneakers and glasses. A wig with sticky-uppy hair (like the young folks are wearing nowadays) wouldn't be turned down, either
• Toad, Luigi, or Princess Peach
• Megaman
• Yuri Gagarin
• Trogdor or Strongbad
• Chewie, Jawa, or Boba Fett
• Nibbler, with antimatter poop
• Link (we have his accessories but not the costume; totally needs pointy ears)
• Wheatly or a turret
• The Avengers: Iron Man, Nick Fury, Hulk, Black Widow, Hawkeye, Loki, or Agent Phil Coulson (we have Thor and Cap!)
• Sheldon (with soft kitty?)
• The Stig
• Vault boy or Vault 101 survivor complete with Pip Boy 3000

UPDATE 5/25: You might notice that most of of our wishlisted costumes are taken (which is awesome), but that doesn't mean we don't want your costume. If you have a costume idea that is not currently listed, sign up and let us know what you're thinking!

If you sign up below, we'll be in touch via email to confirm your costume pick to ensure maximum costume efficiency. (Ten people working on the same costume means we'll have to choose favorites and that's no fun.) And unlike last year, we do finally have Timmy clones handy if you'd like to snag one, but Timmy's measurements are below for reference. (We're out of the freebie clones due to high demand, sorry!)

Timmy's measurements

Height: 8"; Chest (all the way around): 9"; Neck (all the way around): 8"; Arm (shoulder to end of hand): 3.5"; Shoulder to wrist: 2"; Tips of fingers to fingers across shoulders: 10"; Inseam: 2"; Outseam (hip to bottom of foot): 3.5"; Head (where a hat would fit): 8"; Height (tip of head to bottom of foot): 7.5"; Tail length: 5"; Width of face across nose: 2"; Width of feet (so you can get pants on over them): 1.75"; Neck to hip (for shirts): 3". Pretty sure that's every possible measurement, but let us know if we missed one!

Your deadline, should you choose to accept it

Timmy and his entourage will leave ThinkGeek HQ on July 11th, and they'll need a few days to get his bags packed. So the deadline for your costume to arrive at the HQ is July 3, 2012.

Where to ship your creations

Please address your costume to: Timmy's Volunteer Costuming Corps, ThinkGeek, 11216 Waples Mill Road, Suite 100, Fairfax, VA 22030.

Where will Timmy wear your work?

All over the world! At conventions and geeky gatherings, fundraisers, and premiers. He'll debut his new costumes at SDCC this July, though. We also display all of his costumes in our conference room, and in our Timmy costume Flickr album where you'll be credited so that others may bask in the glow of your stunning artistry forever.

That's it! If you have any questions or need more details, please comment below and we'll update this post with the necessary information.

We are already so excited! Thank you, everyone!
