I agree with everyone else. Never too many quilts. You make them because you enjoy and love them so surround yourself with what makes you feel happy. I have quilts all over my house. I might change them with the seasons but I just love to look at them. Telll your relative that it is your house and you love it the way it is and if it makes her uncomfortable then maybe she should stay at her own home which I am sure she has decorated with the things that she loves. :)
