not TOO much wiring or it will weigh the tail down. just use a skeleton base for the tale, (like the outlining of the tail's shape) then cover it with the felt pattern or whatnot, then stuff it ^_^ it should work. and to keep it from falling, you can attach some sort of pin or something that can attach to the back of your outfit.
@teddy: hey do you think we can switch the pokemon time with the kingdom hearts time on day 2? cuz me and kristi have the cosplay contest, and we can't switch into kingdom hearts right after we applied the makeup for the pokemon costumes :/ do you think you can switch them? so instead of 10am can you make it 12pm?
it would really help us a lot! (and besides, you can sleep in longer XD)
