Wherever I go, I cannot resist picking discarded bricks out of skips. I always do it very casually, not only to do a mental check that I'm bending my knees and not my back, but also to convince those passersby who watch you out of the corners of their eyes that you are in fact doing the opposite of fly-tipping.
The oldest shaped bricks ever found (on the site of a Neolithic settlement in Turkey) have been dated to 7,500 BC; poor students and other technically advanced peoples have been building brick structures ever since.
I stumbled across the Instructables / Etsy SewUseful contest at the latest possible moment and in a desperate bid to win a much coveted Singer sewing machine I wracked my brains and remembered the catalogue of useful things I've made using bricks - draught excluders, wine racks, desks and book cases, candle holders etc, etc So, I knew at once that I would have to sew a honest, utilitarian brick.
