I have the two largest Rubbermaid bins full of completed tops (backings are made for most of them). I refuse to count them but I know that there are more than 15. I have finished at least one quilt every month since I retired and have ten ready to show at our guild quilt show in October. My new rule is to finish at least one a month before starting anything new. Sometime I will see the bottom of the bin. In the meantime, I am enjoying quilting and can finish up a quilt in a hurry if I need to and I'm not worrying about the number!
