Suggestions for a straightforward and not too messy craft activity for 7 year old DD's party, please?

[Ceolas]

12 children. They will be all girls except my DS (he's 3 so won't care!). Aged from 5 to 10.

I have a cream carpet in the living room and kitchen is too small. Must be mad!

Hi Ceolas - yes we did - they worked really well, dried well and yes the plates were really cheap!!

OK that's it decided. We'll do biscuit decorating and plate painting.

Tea.

Games.

I love parties. Think I actually get more excited than the children
