Tarzana, Calif.-based Solaractive has introduced an embroidery thread that changes color when
exposed to sunlight. The colors appear as white when seen indoors, but exposure to sunlight causes
them to change to yellow, orange, red, magenta, purple, blue and green. The thread is available on
200- 3300-yard cones. Starter packs containing all seven colors are available. Solaractive threads
can be used with any backing and bobbin threads.
