Shamelessly poached from Refinery29 is this link to a very simple how-to guide on making puzzle-piece friendship necklaces. They're a nice riff on the Swarovski puzzle-piece necklaces that were in vogue a few years back, but much more grass roots. Simply take two connecting puzzle pieces, punch holes, loop a ring through it and distribute. The way I see it, this would make a great DIY gift for someone whose birthday you forgot. It's do-able with minimal tools and materials, and is one of those almost-lame gifts that people can't really complain about, because it's homemade, and it's so touching and whatnot. Of course, just watch. After this post, come my birthday, I'm going to get 100 puzzle-piece necklaces and nothing else.
