Hosting a playgroup/candle party at my house?

so i am hosting a party at my house for my sons playgroup and going to display some of my candles that i have from my home based business. the problem is i am very nervous about it.
i am not sure as what to have for lunch for them, i dont want to do pizza even though that would be so easy but i need to do something easy. there will be a door prize and gifts. i think im nervous because there are other moms who will be there that have held playgroup parties. i know it will turn out well but im still nervous!
any ideas on food to have etc. tips!!!

maybe pigs in blankets, fried mac & cheese balls, french fries, chicken nuggets with different dipping sauces....pretty much anything that is "finger food" and doesn't make a huge mess cooking or eating. Depending on the ages of the kids, I would make it buffett type so they could (supervised) get what they want...maybe make a "taco bar" or "hot dog stand" and let them lead the way.
Make it fun for the kids and the parents will love it, gear it towards your candle business and they'll see right thru it.

Have an assortment of sandwiches and salads. You'll find some good recipes on http://www.epicurious.com/.
