A method for hand-crafting a rug includes obtaining a first sock loop and twisting the first sock loop to form one loop four strands thick. A second sock loop is pushed halfway through the one loop and a new sock loop is pushed through the two end loops of the second sock loop. Additional sock loops are drawn through selected socks and through each other. This step is repeated until a chain is formed. Another sock loop is wrapped around the chain and pushed through one of the additional sock loops. A new one of the successive sock loops is pushed through the first sock loop and a newer one of the successive sock loops is pushed through a space closest to the old loop. The old loop is pushed over the new successive loop until reaching an opposite end of the chain.

A conductive yarn and a cloth containing the same are revealed. A plurality of fibers is wound with a heating element in a spiral form so as to form a yarn with electrical conductivity and flexibility. The conductive yarn is used as a thread in a first direction while regular yarns with conductive metal wires arranged at the two sides thereof are used as threads in a second direction. Thus the threads are woven into a cloth that generates heat while being conducted with electricity. Thereby the cloth can be made into mattress, curtains, textile wall coverings, oversleeves, knee braces, waist supports, foot pads, seat cushions, and carpets etc so as to replace various heating equipment.

An article of furniture is made from elongated polymer filaments. The polymer filaments may be monofilaments or plural filaments which are twisted together and heat set to prevent their untwisting during the subsequent weaving process. The heat setting of the polymer filaments is achieved by heating the polymer material either before or after the twisting process.
