I have only one. It was pounded into me by my parents when I was young that I must finish what I start and that I cannot start something new until I am finished with the previous task or project. I couldn't wait to move out and I did 2 days after HS graduation. Not that I didn't have a loving home and great childhood, but I was itching to do things my way. So I worked that summer before starting college and tried things my way. I guess my parents training stuck because I didn't like seeing unfinished projects or work. So I work on one project at a time but it doesn't stop me from dreaming and planning ahead so I now have about 8 quilts planned with all or most of the fabric purchased and in a separate bag for each. Having many quilt tops completed but not quilted sounds scary to me and maybe my way sounds boring or stifling to you but we each must do what makes us happy. And quilting is fun and satisying no matter what your habits are or how you quilt!
