I'm not usually a huge fan of issuing challenges but here's one I can get behind:
This weekend make some art that is destined for the trash. Don't let anyone else see it or feel free to show it on the ComfortableShoesStudio facebook wall. But set yourself free and see what you learn from creating something without the pressure of making it pretty.
For one weekend make stuff that has meaning only to you.
For one weekend make marks on the page that please only you.
For one weekend mix your paints in colors that you are afraid of.
For one weekend use colors taht challenge you.
For one weekend make a page in your art journal taht you haven't planned out.
Scribble. Doodle. Write.
Do somethng in your art journal that you've never done before.
Set yourself free.
