Tiny, bendy, and absolutely stunning — these 38mm LED filament strips are one of the most unique light sources you can add to a wearable or small maker project. Inspired by Edison bulb filaments, LEDs run along the full length for a warm, diffused glow that's unlike anything a standard LED can produce.
I've used these in several wearable projects and they never fail to get a reaction. They're flexible enough to shape gently or fold slightly, making them easy to embed in costumes, jewellery, and soft builds.
