These offer protection when doing messy or dangerous work, such as cooking, smithing etc. No apron is complete until it's been burnt at least once! The basic apron is much as you would expect, a rectangle of cloth attached to a waistband which ties round the waist. The aprons tended to the fairly thin only covering the front of the body and are generally unpleated. They are made from heavyweight linen, flax or canvas.

Alternatively you could just use an oblong piece of linen tucked into your belt. I recently found this picture a of a man in an apron planting seeds
