I have only been quilting for a little over a year and I could have written your words. Sure, I learn more on every quilt I make but mine will probably always just fall into the "good enough" category. My quilting obession has and continues to literally save my life! It provides me with an outlet to share my love and creativity with others and it is pretty inexpensive therapy!
Hang in there and try not to doubt yourself or your abilities-if you enjoy what you are doing-thats GOOD ENOUGH! I try to only give my work to those that I know will appreciate it and there are plenty of those persons in my life.
