I use the pounce and "mark as you go" when I'm quilting on my longarm. It does work well and I am very happy with it. I've also used the washable crayola markers and I really love those when I want to mark a whole quilt before quilting. I've used them on several quilts of my own and have had NO problems with them once I washed them. It sure made me nervous the first time my quilt was a blaze of orange marker before I threw it in the washer! Came out beautifully though. Whew!
