LED yarn

This LED yarn can be sewn and knitted into clothes or other items. Use it to make light-up shoelaces, an illuminated dog collar (for canines or clergy), or sew it to your backpack to make yourself more visible when cycling at night.

3.3-5V is ideal for powering these LEDs, but remember to use an appropriate current-limiting resistor to avoid damaging and/or shortening the life of the LEDs.

Please note: LED yarn is sold by the metre. If you order multiple, then you'll receive that many metres as a single length.
