How to use the Nontix :
A small bag* (see Drawing No 1) is pinned to the sock just above the boot or shoe (see photograph A), or (better) to the top of the gaiter (see photograph B) on the outside of each leg.
The bag is easy to attach using a small safety pin**, and requires little maintenance other than drying out after use, if it has become wet. It should be stored in a small polythene bag and kept in the dark, when not in use. The lid of your rucksack is fine.
Any cloth material which allows the smell of the marigold to pass through will be suitable. Extensive trials have been carried out with a cotton/linen mix.
**The pin should have a strong spring, ideally a 27mm long, hard wire safety pin. It is a smaller version of the safety pin used in your dry cleaning, and is made by Prym Fashion UK Ltd. It should be available at your nearest haberdashery wholesaler.
