So good to do simple things like these @shibasaki you are truly a great teacher. My first watercolour teacher was a bit of a terror, but in the end I really liked him. He had us all paint crumbled paper bags for weeks as our first use of watercolour ever. It truly helped though, we learned about light and shadow and how many colours exist beyond the 'brown' we see at first.

Good teachers, especially art teachers, are more of what our world needs right now :)
