Paint Looser
Use Your Non Dominant Hand
Wanting to paint more loosely? Try painting with your non dominant hand for a day. This way you won't stay in the lines and you will have more expression to your line.
Here are some things to try:
Spice cans
Kitchen utensils
Things in your purse
Tools
Shoes
Next;
Compose with pencil one of your favorite items
Draw with your dominant hand
Find your color scheme
When ready to paint, paint with non dominant hand and a large brush you don't normally work with.
Do several paintings this way.
