Once I start piecing a top, I stick with it until I am done. If it is going out to a LA to be quilted I start on a new project until it comes back, then I stop whatever else I am doing to get the binding on and have it finished. If I am going to do the quilting myself, I will work on it off and on since I find man-handling the quilt around to be physically tiring..so I may alternate the quilting with work on a piecing top. But otherwise I try to finish each project in order of starting. If I had several unfinished projects laying around it would drive me crazy--guess I am too much of an "A" personality for that!
