I remember making these in my English class with my high school students as a way to investigate feelings and symbols. And they are so magical for that !
The 3rd prompt from Udemy in my art therapy course, this video lesson was great at explaining how to get started and they also provided a handy printable template. I found that I needed some more examples, however, for the specific doodles inside the circles, so I watched this YouTube video, as well (link below).
Hope you get a chance to draw some soothing circles soon, too !!
