Wow guys, knew I could count on you all to give me some fab ideas!
Rikki - those awards are fab, they've got a homemade feel to them, did you buy or make
Magickbean - I do have a nearby Thorntons, I'm not a million miles from you (well, you need to cross the Severn Bridge). I'm a Welshie

You've given me some fab ideas too - sweets!
I normally have two piniatas (can never spell that! LOL!), one for under 12's only, one for later in the night, adults only (sugar burst keeps everyone going well into the night then!). The prize giving would be later again, so more chocolatey goodness will go down well! I can always tart up the packaging on "normal" stuff too I suppose - I imagine black crepe paper bags filled with mini bars would look better than just a handful of bars! (Actually, thats what I do for the trick or treaters, wrap a handful of wrapped sweets and little toys in white crepe and write/stamp "scary" stuff all over it, no reason not to for the "grownups" LOL)
Awesome guys, thanks. Any other suggestions/pics/advice still welcomed though, it seems I'm not the only one finding this inspiring!
