I wanted to keep my valuables safe on holiday, while I sunbathed by the pool. So I cut a towel in half lengthways, then lined each end with waterproof material. Then I folded the pieces to create a pocket and added Velcro to seal them. I can lie it across a sunbed, under a towel and it keeps my phone, books and sun cream safe.
