If I'm going to spend my day woodturning I will wear a turners smock. If, like yesterday I only turned a couple of plane knobs, I stayed in my apron. If I'm welding I wear a leather apron. In this weather I will keep my everyday apron on and wear a jacket which I can take off when I warm up. An apron to me is just a large, ready loaded tool belt that protects my clothes especially when gluing or occasional grinding. It normally only contains a pencil, a white chinagraph pencil, a red fine tip pen, 6" rule, a small square. a 2m tape measure, a rag and a pair of gloves. The workshop is attached to the house so I only have to remove my apron and wipe my feet when I need 'the facilities'.
