We take our collective hat off to anyone who can sew: by hand, it’s fiddly, slow, and frustratingly difficult; with a sewing machine it’s even harder, as the mechanisation element only means that we can go wrong more quickly. So, we’re extremely impressed by The Brick Wall’s sewing machine build, which uses Lego (plus one small rotating handmade part to hook and release the thread) to assemble a working, hand-powered sewing machine. And yes, it produces a perfect chain stitch.
