In one of the Just William books Richmal Crompton lists the contents of his pockets! Mine usually have tissues, rubber bands, receipts, my phone, gloves, a woolly hat, shopping lists, 1p pieces.
The hat is a charity shop cashmere one, so fine and light that it rolls up into my pocket. It has some little buttons on it, the first time she saw it my daughter asked why I had a cardigan sleeve on my head. That made me laugh and I smile at the memory when I put it on. My family find it odd and funny but I no longer care what I look like, it is very warm and cosy. If I had one of the fashionable kind with a big fake fur bobble on top I couldn't get it into my bag, let alone my pocket!
