Meg you should see the picture I have from Hampton court palace workshop Gig I did.
Poi, Juggling, Staff, and a diabolo in my teeth on a rola-bola, balancing a spinning plate on my head and a Gymnasts ribbon stuck in the back of my trousers like a tail, after a kid asked how many things could be done at once - I got loaded up for a laugh (and because the organisers wanted to see too) ... guess what, not looking like an idiot is very VERY hard but that's what I am so why hide the fact eh

Combining props can be cool but it can also go too far (see above description)
