Threads Magazine has once again run an excellent online article that introduces readers to Creating Chemical Cutwork using Fiber Etch
“This fiber remover chemically melts away cotton, linen, and other plant-fiber fabrics. Using synthetic embroidery thread, you can embroider a plant-fiber fabric. Just apply a thin layer of Fiber Etch to the fabric that you want to remove, let it dry, rinse or brush it out, and watch the fibers disappear.”
