I am a part of a homeschool email group that is made up of local homeschoolers and they have two parties a year, for Valentine's Day and Halloween. They reserve a room at a local library and bring decorations and everyone brings food and drinks and games and crafts. The kids are playing monopoly (they look stoked, right?) and we brought our chess board and other games that are popular.
These aren't the best pictures, but it's just to show what the overall atmosphere is like at these parties. They are very relaxed and casual. There are craft tables and game tables set up, and the kids just do what they like. The food table is in the background.
Each kid brought a box and some valentines to exchange and everyone goes home with a box full of cards and candy.
We brought some cupcakes we made at home, some capri suns and chips, and a few games. All our food was eaten, and the kids all had a great time. I was glad to get an invite to this party, as I was just trying to figure out what we were going to do for our own Valentine's party here at home. You can't see it in these pictures, but there is a circle of chairs where a lot of the moms sit and chat during these gatherings.
