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.
