4 wire copper

This Smart Yarn has four highly conductive copper wires. The wires are also insulated with a coating that easily allows them to be stripped by a flame for easy soldering. This yarn is great for prototyping or heating because if used in a sewing machine you have a total of 8 wires conductive wires.  However, if you are sending signal you may experience a problem known as “cross talk” or increased noise to signal ratio.  In that case we recommend our “Smoke” yarn.
