Over on Livejournal's dw_cosplay group, someone called awarmcanofcoke posted a brilliant breakdown of the various greebles on Ace's jacket.

There are sources listed for lots of the bits and pieces, and he's even done printable photoshop reconstructions of some of the rare fabric patches. Just get some computer-printable cloth and you're set!

That post is sure to be a valuable resource for anyone looking to recreate this costume. Now if only he could have posted it last Winter when I started mine, heh...
