Insulation Techniques for e-Textiles
Gella 
Introduction
This tutorial introduces five different methods for insulating conductive thread traces in an e-textile project. All the materials used in these methods can be found at your local craft or hobby store and require no specialized tools.
Why Insulate?
Conductive thread acts like uninsulated wire, which makes it great for sewing components together, but once a project is finished, the movement of fabric can let some pieces of thread accidentally touch. When working with conductive thread, make sure to pay special attention to insulating any power and ground lines so that they don't short out your battery. Insulating stitches, once a project is complete, adds protection from potential short circuits created by movement, folding, or contact with conductive surfaces, as well as adding an extra barrier during wear and tear or washing.
