Biggest tip I can give is: BE PATIENT! Be patient with yourself, with your material, your creativity! Have fun with doing every thing. If you're not it's time for a break. Take a walk. If you have a dog take him/her with you. Look around and see how marvelous this world really is! Relax. The world won't fall apart if you take a bit longer. Don't dwell on a mistake. If I did I'd never get any where!
