Most of us are familiar with pub crawls where you go from bar to bar to bar but end up with nothing much to show for it besides an empty wallet and a hangover.
Sketchcrawls are similar in principle but you spend a day sketching, exploring your city, town, house, garden, wherever you choose to go and fill your sketchbook. You can go alone but there's safety and more fun in numbers.
I will explore this idea soon and take my sketchbook on the road for a morning and afternoon, a day and see what I come up with.
http://www.sketchcrawl.com/ is a great place to visit and see worldwide sketchcrawls. Join in, draw, enjoy.
My sketchpad is always at the ready and here are a couple of samples.
