Quilting has changed so much over the last 20-30 yrs & it will continue to change. Might not be the type of quilting we do now, but it will survive.
In many cases, it's not until kids are grown that we have the time & money to put into a personal hobby.
My feeling is,quilting will really take off into unknown areas if/when the economy gets back to normal.Who knows? The world, it is a changing :)
