I've made it a practice to keep drawing materials on my nightstand, so most of these were made before I've turned out the light.. I have well over a hundred of these and some are terrible but they often lead to better drawings if I keep investigating their leads. Some of these become small paintings or are sometimes scanned to become fabric. When I scan the drawings the fabric website can continue the repeat where I've left off, even if it isn't seamless it's still rewarding.
