I don't hand quilt and even I know what a Aunt Becky's is. The more customers that ask for hand quilting things the more your local quilt shop will carry.
For some people hand quilting will never die. My friend sits in front of a fire place and hand quilts in the winter. That is what gives her joy and that is what she should do.
I am a machine quilter because that is what I enjoy. I am happy on my machine. So that is what I should do.
I greatly admire hand quilted quilts so I hope they never disappear.
