I've been following this discussion with some interest and have been thinking about how to respond.
Part of the delay is that as I'm responding I'm also writing the talk "Quilting is a Beautiful & Complicated Art". While I've had that listed as a lecture for a while - the thought has always been that it's a trunk show however I'm now seeing this, understanding this in a different way.
In and of itself art is as defined by my good friends Merriam- Webster, a "skill acquired by experience, study or observation." Further, "the conscious use of skill and creative imagination especially in the production of aesthetic objects." M-W then goes on to give synonyms such as skill & craft to further define "Art".
When giving thought to all that goes into quilting from choosing fabrics, designs, cutting, piecing, determining batting, & thread design I'd say most quilters by the very definition are artists. Think about the choices we face in each one of those components:
fabric - color, texture, developing an understanding of what works & why
designs - whether changing up someone else's pattern or designing a simple, effective 9 patch there is a geometric understanding of how things work. The more complicated the design, the more the fabric choices need to work together. Quilters often have an intuitive understanding of math, specifically algebra & geometry although a lot of them would say they struggled with math in school. We problem solve, figure out how much yardage we need (algebra) & the geometry is a little more obvious.
cutting - accuracy is essential the better the cutting the better the quilt
piecing - piecing well taking time & care gives insight into how much skill a quilter has, it's why we admire the Amish so much, their skill level is often off the chart. Yes the patterns are not complicated however they are accurate. Then there's all the different kinds of piecing with pins, without pins, foundation piecing - including paper or fabric, appliqué (raw edge, fusible, needle turn, etc)
batting - has an effect on the look of the entire quilt when we're finished, we have to give consideration to loft and how we want that loft to effect the look of the quilting when we're finished
thread design - thread weight, color and type all have an effect on the look of the quilt. We can hide or highlight piecing issues here.
I've also been thinking about what kind of quilter I am and I'm going to start a new movement and define myself as a quilter - I'm not traditional, though my work has tendencies in that direction; I'm not contemporary (though by current quilting definitions that certainly seems to be my niche) I'm not an "art" quilter as currently defined.
I am an artist though as consistently defined by Merriam-Webster. I spend a lot of time & energy honing a craft that I love, that is my passion and in that I have a lot to offer as an artist and as a teacher.
As far as I'm concerned Eileen as long as you are constantly working on honing the craft in a style that gives you a sense of satisfaction or fulfillment I'd say you're an artist. If working with "traditional" patterns offers you that life-giving joy then hone your craft in that area. Just as there are different styles of painting, there are different styles of quilting.
