Halloween party ideas

Im having a halloween/costume party for my 18th birthday {which is the day before halloween}
What are some good ideas of what to do, like food, drinks, decorations, invitations, etc...

Must have green jelly, those fake teeth lollies, 'blood' red wine, pumpkins. Cob webs are easy - you can buy spray can cob web stuff and just spray over door ways etc. That's about all I can think of - I actually started out this reply thinking I would know heaps of ideas but I don't - sorry! Sounds like a blast party tho!

Go to google and research food ideas. That is what I did last year for my boyfriends 20th bday which is the 27th of this month. We had apple slices that looked like fingers and stuff like that.
Actually, I'll just funmail you some things.

thanks.
I googled a bunch of stuff.. and found a bunch of things, but I wanted to get some more ideas from people on here :]

carriedee, I've never seen that spray can cob web stuff... but I will have to look for that!
