How SewGlo™ Works

01
Sew or Embroider
SewGlo™ runs through a standard home or industrial sewing machine just like regular thread. No special tools needed.
02
Connect to Inverter
The thread ends connect to a compact EL inverter, battery powered, pocket-sized. Connection takes about 2 minutes with the included connectors.
03
Switch On
Flip the switch and the thread glows. Uniform light along the entire length, no hotspots, no batteries sewn into the garment.
04
Wash & Repeat
Remove the inverter, disconnect the thread, and machine wash as normal. SewGlo™ survives regular wash cycles without degradation.
