Exhibition curators often face a funny dilemma: The more successful they become, the more great people start clamoring be involved in their projects, which ultimately only makes their selection process that much harder. Hence why the minds behind the Swedish design auction Örnsbergsauktionen — which for the past four years has consistently been pretty much the most amazing thing coming out of Stockholm Design Week — decided to tighten the curatorial reins this year, not only requiring that their 30 participants be designers who self-produce their own work in small batches but also leaning heavily towards the ones who work collectively or invent their own materials and processes. Once they managed to narrow their list down to the lucky few, which this year includes folks like Maria Jeglinska and Jenny Nordberg — plus of course founders Simon Klenell, Fredrik Paulsen, and Kristoffer Sundin themselves — they let the magic flow, resulting in the 40 objects that will head to the auction block on February 6. As usual, we've excerpted our favorites after the jump.
