To everyone comparing their own talents to these....don't do that to yourself! I did it the first year I went, also. Then I realized that the people who enter these shows are very exceptionally gifted artists...no different from artists using other mediums, ie photography, paint, clay, etc.
I am not an artist, I am a quilter. I have good quilting skills, but not artistic talent. I don't compare my work to theirs any more. While I can appreciate their work, I don't aspire to it.
Embrace your own skill at the wonderful craft of quilting. It is indeed an acquired skill...practice, practice, practice. As you go along increasing your skill, you may turn into an artist, but don't count on it. Only a very few can turn out works of art in fabric. The rest of us can turn out beautiful quilts for our friends and family to enjoy. This is my forte...and I am happy here in it!! :-)
