(I don't have very high hopes for it, but I was curious and ended up getting it for Christmas. The last giganto-compilation I read was by Arthur C. Clarke, and just about nothing can live up to that.)I also sew, constantly but not very well. I passed my 20th cosplay assignment in 2006 (I'm ugly as hell, so I mostly dress up prettier people), but my enthusiasm for that has waned because it's a relentlessly perfectionist and thankless money pit of a hobby that only the very, very bad and the very, very good can actually enjoy. Kinda... kinda like AMVs, in that way.
(I kid, I kid. It's hard to find that devil-may-care attitude with regard to cosplay, because the product is you and not something you've made. I find it hard to achieve the necessary distance.)My younger sister and I also have a collective obsession / hobby / sidetrack making cosplay-like deelybobbers and whatsits. Our next deadline is in 12 weeks, so uh... the world should be relatively free of me until after that.
Currently working on an Ouran High School Host Club teddy bear, which is a no-brainer.I enjoy quilting, but it's been sidelined for the last couple of years because of the cosplay / Artists' Alley stuff. Started to learn how to knit, but I can't seem to purl and kinda shelved that until I have more free time which may be NEVER ARGH.
I enjoy cooking, mostly vegetarian, because I dislike raw meat. Savory baking is my favorite - bread and biscuits, stuff like that. And trying new things.
Of course, playing video games. Mostly console RPGs, Japanese style, with a smattering of other ones, like Okami and the odd rhythm game at which I suck but play anyway because it's fun. I also have yet to find my equal at Karaoke Revolution. I have a horrible voice, but because of the way they score, I own that game hard. It's embarrassing.
My annoyingness isn't a hobby; it's a disease.
ohh!.... 
I think I second the motion XDD
