KIRK, Stella, South African. In 1960 she patented a dish-drying rack, which she called Eff-y-Co. It copes with all dishes for a large family, and involves elastic springs enabling expansion for extra crockery to be held. It is polythene coated and in attractive colours. The design caters for wall mounting or use on a draining board. The family opened a factory and now sells such products to most countries in Southern Africa.
