I feel for you about the dog house. I had a quilt sale once and it was under a pavillion and a lady came in with her small dog and it cocked its leg and peeed all over a white and pink double wedding ring quilt. Luckily I saw it and when she went to walk away and leave, I called her back and she had to purchase it.
But the one that comes to mind is a queen size quilt I made for my son and his fiance. I had 80 appliqued hearts on it, every one of them different and while she was studying one day on her bed, she had her little 4 yr old there coloring. She looked up and here the little girl had colored all over the top of the quilt in permanent markers. The background was white and it ruined the quilt. That relationship did not work out but my son still has the quilt on his bed so for Christmas this year he is getting a French Braid quilt that is more masculine done in oranges (his fav color) right up to rust with the accent color black. Can't wait to replace the old one.
