These are free events that people do not think of as events, which is exactly why they are hard to find. They are also the most reliably available thing on this calendar: standing weekly shifts rather than one-off dates, running from spring into late autumn. The catch is capacity, not cost — the good ones fill a week ahead, so book rather than turn up.
The rest of what’s free
The good ones sell out.
Follow a craft and we'll email you the moment a new class or registration window opens — before it's gone.
