FMQ on a LA is almost like doodling, and it is a matter of time before you find your favorite quilting designs. I practiced on large sandwiches which eventually became totes, hot pads, and so on. The dog bed mentioned in one of the posts above is a great idea. I did one large sandwich with pretty fabrics on both sides, and one side was one color so that I could see my practice designs all mixed together. I made a quilt carrier out of it and I am always surprised when I open it and see those designs. They came out pretty good.
