If I can make it to Kcon, I probably won't be doing anything new -- it's my last con of the year, and by that point I've pretty much got everything I want for the year ironed out. That said, I have a crapton of work to do and it's aiming for Sakuracon, so oh dear already.
Right now, most of the work I've been doing has been for my Trinity Blood cosplay (Kaya Syokka/Gypsy Queen -- hurrah for the obscurity of novel-only!). Supplies are by and large amassed; I picked up hoops at Faire this past weekend, so the only things I might need are some more petticoat fabric, Wonderflex, and of course resincasting supplies (and possibly paints; not sure about that yet). I've done a bit of the Wonderflex armour for the boots and built the rosaries, but that's most of it for now.
In fact, most of my cosplay stuff is practically on hold right now. T_T I'm hopefully moving in about a week, so once that's done I can get back to work, but for now almost everything is in boxes (or should be going into them).
