I made a pencil sketch whilst having a tea session. It took slightly longer than I anticipated, maybe 4-5 hours. 0.5mm propelling pencil with a B lead, on good quality rag paper.
The tea was an aged High Roast Luanze Oolong from Nantou (700m), Taiwan, Harvested in Spring 1999. Brewed over two sittings first in a zisha, then zhuni teapot (I found the zhuni a better fit in this case). The tea (as ever…) was courtesy of Stephane at teamasters blog
