The turning points this atlas records in the history of craft and hobby practice: the Penny Black, the Great Exhibition, the Leach Pottery, the Whole Earth Catalog, the Etsy launch and the first Maker Faire among them. A milestone here is a dated event or publication that changed how a craft or hobby was practiced or understood, not the ongoing institution or movement it may have helped found, each described in its own right and linked back here by relationship.
