What They Don’t Tell Engineers About E-Textiles

Jessica shares her experiences from her first e-textiles project and offers some helpful tips:

In my first E-Textiles experience, I definitely learned quite a bit about the “soft” side of soft circuits. Some of this may seem like common sense, but for someone who has never sewn much of anything, I most certainly learned some lessons.

Choose your Fabric Wisely

For this project, I just picked up the first suitable T-Shirt I found from Target. However, the fabric was incredibly thin and stretchy so when I took my carbon copy pattern off, the fabric scrunched together and I had a couple of shorts. When I wear the shirt it gets better and stretches out, but I would certainly choose a thicker and less-stretchy fabric next time.

A different fabric would have also allowed me to keep my stitching neater on the back of the shirt as well, allowing me to better keep power and ground threads separate.

Mark your Thread

Even though this is a simple pattern, I quickly lost track of which tie-offs were ground and power. When breadboarding or soldering to a proto board, I can use different colored wires to separate connections. With E-Textiles the thread is always the same color, so making a black or red mark on the thread would certainly help.

Use an Embroidery Hoop

Maybe it was because I was using a slip of carbon-copy paper instead of tracing paper or maybe it was the fabric, but it was incredibly tricky to keep the paper precisely lined up with the fabric – even after using several pins. When I was a kid, I used to do cross-stitches with my grandma over summers in Wisconsin, and we used an embroidery hoop to hold the fabric in place. I kept thinking as I was sewing that it would be incredibly useful, so I plan to pick one up and use it in the future.

Start Big

Normally the advice for starting a new hobby is to start small, but in this case a larger pattern would have been much easier to work with. The pattern I chose was relatively small, so it required some maneuvering and it was tricky to place the thread to avoid shorts. In the future I’ll be able to match fabric choices with pattern size.

Great tips! Thanks, Jessica!
