We did an early Christmas here last year, I got the kids to make the Bon bons, for the table cloth I used butchers paper (actually it was the art paper from ikea), table decos, was a gingerbread house the kids and I made, jars full of christmassy pencils, and tree decos.
For our meal I did a couple of salads, a ham, turkey, and pork I think. We cooked all meats the day before and served cold (or reheated that day, honestly cannot remember) and dessert was a pav, gingerbread house, and some choccies. Yep it was a fairly laid back day.
I will always host it again, dh is an amazing chef, his food beasts all other family members and best of all his food is edible and doesn't gift food poisoning
