The Instructables

Heavy Petal readers, meet Instructables. It's a website devoted to collaborative DIY: participants show (step-by-step!) what they make and how others can make it. The "what" varies widely: from how to make a marshmallow gun to how to sew your own bra to how to divine water.

At the moment, I could only find one garden-related article: how to root plant cuttings. But hopefully once the site grows (hardy har har), more gardeners will contribute. A good one to watch.
