Hollow green is a type of embroidery that uses a special needle to create raised, three-dimensional designs. It is often used to create intricate designs on clothing, accessories, and home dcor. The hollow green technique is said to have originated in China during the Ming Dynasty, and it has since been adopted by artisans around the world.
To create hollow green, the embroiderer uses a special needle with a hollow shaft. The needle is threaded with a single strand of embroidery floss, and the embroiderer uses a series of stitches to create a raised design. The stitches are typically very close together, and the floss is pulled tightly to create a smooth, even surface.
