DD1 turns 13 in a couple of weeks and really wanted to take some of her friends to a Chocolate Workshop, where they get to make/decorate chocolates. But they are so expensive - about £30 a head - so we thought we'd do it at home. Melt some chocolate, pop it in a mould, a few sprinkles....how difficult can it be? 
So I'm looking for inspiration/ideas/suggestions about how to do a Chocolate Party at home, for about eight girls. What to do/what to make/where to get the necessary equipment. I picked up a few bits and pieces in Lakeland but really need to devise a couple of easy "projects" for them. Suggestions welcome!
