Christmas is coming, the geese are getting fat. Grab yourself some bubbly, and try to make a hat. Lizzie Lock leads this masterclass in millinery ("hat making" after a few glasses) at Clerkenwell's 155. With all the materials and a couple of glasses of bubbly included in the ticket price, there's never been a better time to do it yourself. Who knows, if you've got the knack you might find yourself with a gift for a dearly beloved at the end of the night. Hope's a fine thing. Over 18s only. Valid ID required.
