Woo-hoo! Have solved the blue skin problem! I got some water-based moisturizing lotion to rub on my skin beforehand (it doesn't hurt at all when I peel it off now!), then got some talcum powder to dry up the latex so that it won't stick to everything. The result is a beautiful slate-blue color, and I now have the confidence in knowing I can touch stuff and go about my everyday life without worrying that I'll mess anything up.

I haven't tested it yet, but when I was at Utrecht today, I also got some blue acrylic paint that's just a smidgeon darker than the latex color. I'm going to go all-out and draw in the scars as well. :D This is going to be so amazingly cool... Now only one question remains. Where the heck do you find elf ear tips?
