I often do a savory plate for kids parties, where I cut out a heap of pieces of bread into star shapes (using a cookie cutter) and toast in the oven, then do star shaped cheese and slices of cold meat, and small pots of dip. If you are allowed tooth picks, pop a tooth pick into each piece of cheese to make a small 'wand' and then stick them into a half an orange to stand them up! You can probably get a large carrot or cucumber and do little mini stars too, the kids love the different shapes. Another fave is get two slices of bread, spread one, with whatever you like, butter the other, then on the buttered one, cut out a shape (ie: letters, stars, Xmas tree) then place butter side down on top of the spreaded slice, so you have a sandwich with a picture IYKWIM?!
