Below is my second attempt at tangling a gourd. I used a dark brown Micron pen (from Sakura), and a red ProMarker (from Letraset). There were two challenges; first, I found it difficult to draw precisely on a rounded surface. Also, it takes a while for the ink to dry, so you have to be careful not to smear the ink with your hand.
This was a long-distance play-date with two of my artist friends.
