Checking for Conductive Thread Short Circuits

Watch out for any loose threads or knot tails in your project. If any piece of the conductive thread from the positive (+) side of your circuit accidentally touches the negative (–) side, it can cause a short circuit. A short circuit connects the battery to itself and bypasses the rest of your project causing an unwanted amount of current draw from the battery. Stitching directly over stitches in another part of the circuit can also cause a short.

It’s important that your stitches do not cross over each other or touch other parts of the circuit. The batteries used in these projects shouldn’t burn or shock you if they short circuit (although they may heat up), but higher voltage projects or power sources could be dangerous.
