I feel that quilters will just think more before they buy fabric, really work out what they want to make and lets face it, we are all prone to adding to the stash without thinking. Good quality will always win, and quilting has been going for a long time and has survived wars worldwide so it will survive this too. Shops will probably have to rely on more teaching to add to their income. In my country quilt fabric is very high priced compared to yours and we all still quilt. I guess we just have to be careful more with what and how much we buy.
