I had a crafting party for my ds. Although he was only having his 5th birthday, I think some of the ideas would go down well with older ones.
We had three activities, with dancing in between while we cleared and set the next. We had card blanks on the table with glitter glue, sequins, buttons, threads, crayons, pens etc. Then we had plain baubles with decorations to glue on. Then while these were drying off (on racks made from the holders of 24 bottles of fruit shoot - ideal for drying baubles!) we had cookie decorating.
I made cookies in a variety of shapes (car, man, woman, house, heart, etc) and put on the table little pots of royal icing that I'd mixed up the day before, and various sweets that were the right colours and sizes for decorations (it's much cheaper than actual decorations) with a plastic knife for each child. I brought writing icing with me too but I forgot to put it on the table - it didn't seem to matter! The children enjoyed that and what's more, they cleared up that activity themselves, by eating the results!
