Check out the tutorial by Feline Fanatic ..here is a link. I think it helps to plan/doodle/sketch ideas. She uses paper..I often use waxed paper. I also practice what I am planning to quilt on a white board. Dont' put your elbow down-you are training your arm and shoulder. Can't wait to see what you decide!

PS I 'see' quilting designs EVERYWHERE! I have been known to talk pictures of walls, carpet, bags, tshirts...whereever I see a pattern! You just never know when that design might come in handy!
