If it’s your first time out and you can’t spot anyone at 2pm, just choose
something to sketch and get stuck in. Keep your eyes open for anyone carrying a
sketchbook and say hello. It's a friendly crowd who you’ll get to know over a
drink from 4pm. Don't worry if you're late, most of us usually are! You need to
bring your own paper and pens/pencils etc.
