Step 1: Gather Parts
Step 2: Sew Conductive Thread to Ribbons
With a zig zag stitch sew conductive thread to ribbons.
Step 3: Tailor Tack Ribbon Array Together
Form an array by tailor tacking the conductive thread ribbons together.
Negative ribbon with conductive thread facing down.
Positive ribbon with conductive thread facing up.
Loosely sew the ribbons together at crossing points.
Step 4: Slide LED Legs Into the Array
Gently bend the legs of the LEDs.
Slide negative leg into negative trace zig-zag by puncturing thru the ribbon to reach the conductive thread zig-zag channel. Feed the negative leg thru the channel making contact with the conductive thread.
Slide positive leg into positive trace zig-zag channel making contact with the conductive thread.
Gentle snug the LED into their zag-zag channels.
Step 5: Connect to Power Source
Make a master positive ribbon trace and a master negative ribbon trace.
Lay the master negative trace on the negative array ribbons with conductive thread touching.
Using conductive thread sew the negative traces together.
Lay the master positive trace on the positive array ribbons with conductive thread touching.
Using conductive thread sew the positive traces together.
Connect master ribbon traces to power source.
Let there be light!
