Artisphere turns one! Celebrate this weekend. (Jonathan Newton/THE WASHINGTON POST)

This year, use the force. The Rebel Legion and the 501st Legion will be at the Arlington County Central Library to teach you how to make costumes based on your favorite “Star Wars”characters.

Now that you’ve got that out of the way, and well in advance of Halloween itself, you should party. Artisphere, the huge Rosslyn cultural hub, is celebrating its first birthday with a party featuring a site-specific video work created by Brian Stansfield and music from Volta Bureau, Alvin Risk and Hays Holladay.

While Artisphere’s birthday party may soon become a tradition, one that has been gone for eight years is making a return. Taste of DC is back this weekend with dozens of restaurants serving their best dishes over three days.
