Every year we have an end-of-year sort out of the attic and the warehouse, rummaging through heaps, bundles and boxes of experiments, disasters, slightly dinged-up trays and boxes, damaged patterned paper, mislabelled notebooks, discontinued printing blocks, redundant lampshades and things we gave up on long ago, sometimes for reasons we can no longer understand. It’s a glorious jumble that must be banished from our workspace so that new things can take shape there. None of it can be sold in the ordinary way as every item is different (heartfelt apologies to those who cannot attend in person — for this reason we just aren’t able to run this event online) but it all has potential and we very much do not want it to end up in a skip.
