It is ok to print with the same colors and subject matter! All the famous artists do it.
I love blue and yellow. And I really love printing with thin flat weeds and grasses.
Today I challenged my readers to pull 10 prints. I often do this for myself when I just need to get started. Before I know it I have a pile of prints and even a few that I like.
I invite you to drop everything and go pull 10 prints. Enjoy!
