The substation is a fantastic venue and the market is chock-o-block with talented artists and craftspeople. Worth a looky.
If you're interested in a spot of life-drawing, Leonie runs a group on Saturdays where you can drop in week by week - without having to book in for a full course. It's a great way to try out something new and creative (or scrape off a bit of rust that may have built up since college days). There's always great food and fine company, to boot! Contact Leonie through her blog for more details.
