Palm leaf Pattachitra in Oriya language is known as Talapatrachitras drawn on palm leaf. First of all palm leaves are left for becoming hard after being taken from tree. Then these are sewn together to form a canvas. The images are traced by using black or white ink to fill grooves etched on rows of equal-sized panels of palm leaf that are sewn together. These panels can also be easily folded like a fan and packed in a compact pile for better conservation. Often palm-leaf illustrations are more elaborated by superimposing layers that are glued together for most of the surface, a part of which can open like small windows to reveal a second image under the first layer.
