ABSTRACT:
A decorating process including the steps of 1) providing a length of heat shrinkable tubing having a lateral insertion slit formed along the entire length thereof into a passageway running the entire length thereof, 2) positioning a length of electrical cord laterally through the lateral insertion slit into the passageway of the heat shrinkable tubing, and 3) applying heat to a top section of the heat shrinkable tubing located opposite the lateral insertion slit for a sufficient time to shrink the top section of the heat shrinkable tubing. In a preferred embodiment, the heat shrinkable tubing provided includes an outwardly directed interlocking lip defining one edge of the lateral insertion slit and an inwardly directed interlocking lip defining an opposite edge of the lateral insertion slit. The outwardly and inwardly directed interlocking lips are interlockable to maintain the heat shrinkable tubing closed around a length of electrical cord. When this type heat shrinkable tubing is provided, the process further includes moving the outwardly and inwardly directed interlocking lips into interlocked relationship. The heat shrinkable tubing can be provided in any desired color and, if desired, can be provided with an exterior surface embossed with a pattern such as a wood grain, a holiday pattern, snake skin, etc.
