Graffiti art party
Might not be possible for winter because you can’t spray paint in certain temps, but looked really fun.

Beat Ya Feet Dance Class
This is a style of hip hop to GoGo music. Very DC and looks so fun.

Screen printing class
In 5th grade I had a screen printing party for about 20 girls. They made screen prints on paper and then made tote bags. Was a lot of fun. Sorry we weren’t DC area then, but someplace like this:

Small group ideas:
Theatre - musical - concert - sporting event tickets
Slightly bigger group:
Mall/ Bethesda / DC movie in theater and fast casual (Chipotle/ Cava type) meal
Outdoor ice rink (sculpture garden one is pretty)
Hot cocoa/ Starbucks and cupcakes
What are your daughters likes/interests?
