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.
