I have decided to be Thing 1 for Halloween this year. I have a nice roundish 3c fro of hair. I want to just wear it down and make it really unruly as opposed to wearing a wig (what's the point when I have natural craziness?) But now I have to make it BLUE. I can obviously get the temp hair spray but I hear that's really messy. I was also thinking of just getting some kind of doo-dads to put in my hair like feathers or streamers or tinsel that's blue. I can't dye my hair because of work. Any ideas? or feedback?

p.s. this is the hair i'm working with (just add a years worth of growth to it as this pic is a tad old)
