if you're specifically wanting to make things, you could do pinwheels, vol-au-vents, mini quiches, or mini kebabs (with cantelope and proschuto (sp?), or bacon and prunes, or cheese and kabana and ****tail onion, or tomato and basil and boccachino (sp?) or whatever ...

if you're happy for it to be more laid back, you can do what I'm doing:-

1. one platter with different nuts and mixed fruits
2. one platter with different shaped pretzels and crackers and cheese cubes
3. one big bowl with mixed christmas coloured lollies (spearmint leaves, jaffas, and white chocolate balls) with some chocolate and marshmallow santas thrown in
4. one big bowl of veggie sticks (carrot, celery and capsicum) with two dips.
