Some of watercolour tutorials are done using the computer while others are done with paint and brush in hand. I tried to find some that start with the basics to others that are a bit more advanced, but still doable for beginners.
I LOVE this portable water brush. It holds water in it's body and you need to squeeze it to release water and mix it with paints to use. Very useful to have a quick watercolor sketch. Sakura Koi Watercolour Field Sketch Set
