Mindful Painting with Cecilie Okada
There are numerous tutorials to choose from: a flower, a leaf, a bird, an illustrated letter, or a landscape. Browse through Ceci's blog to find the one that most appeals to you. Each tutorial comes with a free outline that you can trace and transfer, so you don't need to worry about the drawing part. Below are some art supplies you will need:
The quality level of the art materials is entirely up to you. Price reflects quality. Amazon Japan has everything you need.
If you want to go to an art-supply store, Yuzawaya in Sannomiya, Kobe, is great (in other cities NOT so much). In Osaka or Kyoto, Kawachi is a specialty art-supply store. Ceci has a guide to art supplies on her website, but the links go to the Amazon US.
