It's amazing, and sometimes amusing, what we modellers find in everyday products that could be useful in our hobby.
Just today, I was about to throw out a couple of broken, plastic clothes hangers, the type with clips to hold trousers. I realised that the "clips" can slide off the hanger, and will make excellent clamps, being spring-loaded and with rubber pads in the jaws, great for clamping wings together or similar items.
