This quote is right, not just for teachers but also for everyone. We teach others in different things, the same time we learn from what we teach. Everybody is a teacher, not by the profession but in the real life on how we can stand from the experiences we had and learn from it.
This is my calligraphy, a skill of writing with style. It is the design and execution of lettering with a broad tip instrument, brush, or other writing instruments. But I love to use brush calligraphy, difficult but challenging to make. I made it 6 months ago and I had deleted the step by step pictures on the process on how to make it.
This is the process on how I did it. First I prepare Canson watercolor paper with 200 gsm with the size of 5x7 inches. I used the simbalion watercolor and I paint it like a night sky . From the dark part to the light part and then I paint the pine trees in black. I write the "quote" with a pencil as a trace, then I used brush and white poster color to write those I traced. I also used Uniball signo white for the bright stars. I just spatter white poster color on a flat brush to create a starry night effect.
