So she is shocked because she has five finished (maybe) and you have 15 you enjoy. Its your house and your rules until she moves in and takes over...Enjoy. Each to their own.
I have a number of unfinished tops because I have not learned to do them with my old Bernina and cannot afford a LA to machine quilt them. Maybe someday that has not come yet. I still enjoy doing the different patterns and colors in quilt tops. Go for it and SMILE.
Turn the other comments into a humorous reply and laugh. Quilts are suppposed to be finished??? Mine are the way they are loved.
