I have started Ria Sharon's Sketchbook Magic class. She encourages opening your mind to anything: any material, any shapes or marks. The only thing she won't tolerate is excuses. She wants students to commit to a drawing a day.
I admit that it's hard sometimes, but just taking the class pushed me to draw without any expectations of the finished product.
I did this little doodle at Panera for my Day 4, #MakeArtAnywhere challenge.
My Kandinsky book quietly whispered that I could do it!
Ria has a calming voice and positive energy. I encourage you to get a Skillshare membership and take her class as soon as possible.
