For me, I think it is the perfectionist in me. I guess I am always in search of the most perfect, most beautiful, most well done quilt. No pressure here. I find that I always LOVE the quilt that I end up with. And almost always it is not exactly what I thought it would be when I started. I've been doing this for about 30 years. I'm a happy quilter. Just don't get to do this enough. :)
