Adding our LEDs to our fabric

In the same way that we stitched the ground or negative connections of our LEDs together in Chapter 3, Sewable LEDs in Clothing, we are going to use a common ground connection for all of the negative connections of each color LED. Starting with the red LED furthest from the poppers, place your LED on it's marker on the piece of the fabric and stitch it to the fabric using a long length of conductive thread stitching through the negative connection of the LED. Continue with the same piece of conductive thread, and stitch a running stitch along the marker line on your fabric, and then use this to attach the negative connection of the next LED. Continue doing so for all the red LEDs, and finally, run your conductive thread to a female half of a popper, and stitch this to its marker on the fabric. Finish attaching the popper to the fabric by stitching...
