I've recently stepped up my search for more examples of objects that resonate with Enzo Mari's autoprogettazione model: artists and designers who offer not just the non-authorial conceit of "made by anyone," but "permission to make it yourself." It's a surprisingly fine filter that keeps a lot of nominally instruction-based pieces off the list.
Anyway, I'll make an open plea later. Right now, though, I'll just give NY designer Lindsey Adelman a huge high five for publishing her "You Make It" chandelier. Adelman's main practice is creating intensely produced chandeliers and lighting made from custom, modular hardware systems and handblown glass. They're several thousands of dollars, and it shows.
Which makes it remarkably easy for Adelman to be so generous with the level of detail she offers on technique and parts sourcing for a $120 You Make It option; despite the beauty and conceptual similarity, there is no mistaking the one product for the other.
