Abstract

A novel decorative structure includes a length of strand material, having a plurality of individual strands twisted with respect to one another and fixed with respect to one another near a first end of the strands, and a twisting member having a plurality of apertures formed therein, each adapted to receive a respective one of the individual strands therethrough. In a particular embodiment the twisting member is a disc, such that when the twisting member is advanced from a second end of the strands to the first end, the strand material is caused to unwind. Similarly, when the twisting member is advanced from the first end to the second end of the strands, the strand material is caused to wind up. When unwound, the strands retain a decorative helical shape, and give the appearance of a Christmas tree.
