The drawstring stops dust and bugs getting in and allows the bag to be hung up in the fresh air as well as stopping the gear inside from falling out!
All the contents should be made of strong material such as metal or melamine to avoid breakage and should be CLEARLY LABELLED!!!!!
The easiest way to make a dilly bag is from a pillowcase or cotton bag from the supermarket with drawstring sewn in.
The contents for Dilly bags can be easily purchased from the Scout outdoor centre
