In making this project I needed to use an insulated yarn.  Most conductive yarns are uninsulated, which could cause shorts, especially when knitting on a small, close scale.  Current commercial insulated yarns usually have a polymer sheath.  Although strong, this material does not offer other potentials of natural fibers such as wool to felt or provide heat resistance. 

To create this conductive material for this project, a yarn was made by spinning wool thread around a conductive thread core. A modified rope machine was made to create the insulated yarn. Six strands of thread are wound separately and then twisted together around a conductive core thread to create a single piece of yarn.
