Wow... I know how that goes. I was telling someone when I first started that I wanted to finish what I was working on before I started another quilt. The sales girl laughed at me as though I told a funny joke.
I have relatively stuck by that. I made two very pretty rail fence lap quilts 2 years ago. One needs the binding redone, one needs to be finished machine quilted. But I lost them in a big move a year ago. So now, I only have the one I'm working on. I have plans in my head for 3 more, but I work strictly one at a time. I have 3 small children, husband, and all the household things that keep me so busy that I cannot afford more than one project at a time.
