I think we also have to consider our reasons for quilting and what is our desired goal. In many ways dealing with my vision and other issues, I feel my "best" quilting is behind me. Or maybe it is just my fussy old school choices that are behind me. So no New York Beauty or Pickle Dish on the to-do list, and although I think I will someday make a pretty great Mariner's Compass, the current project scope is much more limited than original plans.
So my goal for quilting is an artistic expression for me, but a craft project as a result. For me, a quilt is a craft -- a usable object that I can use and live with art on a daily basis. I am not making them for the next generation but for the current recipient and my goals are "machine sewn, machine quilted, and machine washable".
An award winning quilt may also be all those things but not really meant for the day to day practical living with pets and worries about spills -- projects that have to be handled with gloves and kept out of the light, and refolded and correctly stored with muslin or acid free linings every couple of months. I say that isn't a quilt -- it's a pony! There is absolutely nothing wrong with textile art and I'm constantly amazed by the skills of people around me, but it's not what I do and it isn't how I grade myself.
So for what I do, I consider myself extremely knowledgeable and proficient/above-average skills for what I do -- but there are a lot of things I just don't do. My skills are high even if my fabric selections are "taste specific", not everything I make suits my tastes either!!
