The format is a hands-on art workshop centered on building 3D paper flowers — sculptural, not flat-craft. Paper flower construction has a legitimate learning curve around shaping petals and layering depth, so this isn't a sit-and-color situation. It's the kind of skill that transfers: once you know the folds, you can scale up or down for centerpieces, wall installations, whatever. Free workshops like this tend to run on donated or provided materials, so you're not buying a supply kit at the door.

Practical notes: these sessions usually cap attendance, so RSVP or register through the SFFuncheap listing if that option exists. Wear something you don't mind getting glue on. Arrive five minutes early — free art workshops fill from the front and latecomers often don't get a full materials set.

If you've got two hours, do the workshop start-to-finish. The takeaway is a finished piece, which is a better souvenir than most free events offer.
