don't let people crush your artistic expressions. finish this quilt exactly how you wanted it to be.
i make art quilts and most people don't like art quilts they like the traditional homey stuff but that doesn't stop me from doing my art and exploring my talents and abilities.
art is a very personal thing and what you make will not be liked by everyone because we all have different tastes.
this should never stop you from working - go back to the original design you had in mind and forget what any one else has to say about your work.
