Welcome from Beautiful Arizona.
I doubt any of us began with a "masterpiece" so don't give up on quilting. It is a never ending learning process and that is one of the beauties of it - always learning. I am an artist, painting mostly in oils and I have yet to paint my "masterpiece" there either, but I keep at it. LOL
Must note that your fabric choices are wonderful. See, you have a talent for quilting that you may not have thought of - putting fabrics together for wonderful quilts (quilting.)
