Alison,
Thank you for starting this thread and I will keep following hoping that you will share any response you get from Henry with us.
Also, I love the diversity of this board! When I go to quilt shows, I really enjoy the artistic talents that you have on display and I get ideas everywhere. BUT, as your quilting sister, you'll probably never see a quilt of mine there not that I wouldn't love to be able to create something that lovely. I am content to create mostly simple quilts that little kids sometimes call their "cover" or "covers" that will be privy to all the chaos that can exist in a child's life. So, they'll see the washer/dryer often especially after they have already been in "hot water" and need a laundry trip!
If I made or even owned one of those beautiful quilts some of my fellow QB members make, I'd hesitate to wash at all. They are true works of art! I am celebrating the diversity we share and appreciating the inspiration that other quilters bring and so willingly share!
