Abstract: A method of sealing an opening on a waterproof covering for a limb. A first step involves providing a waterproof covering having an opening with a peripheral lip. A second step involves placing a form fitting waterproof elasticised sleeve around a limb above an upper  extremity of an affected area to be protected from water on the limb. The elasticised sleeve prevents water from getting to the affected area by passing under the sleeve. a Third step involves placing the waterproof covering over the limb with the peripheral lip of the opening encircling the sleeve. A fourth step involves folding an exposed peripheral edge of the sleeve over the peripheral lip. The peripheral lip is sandwiched by the sleeve with the positioning of the sleeve preventing water from entering into the opening.
