There is a quilt and furniture auction run by the Amish community near where I live at least once a year. A couple of years ago, they started showing certificates of "authenticity" with quilts that are completely made by the Amish before the bidding started on thos quilts.. It was amazing how many quilts did NOT have the certificates.
I've recently heard of quilts that are pieced by the Amish and shipped to China for quilting!
LET THE BUYER BEWARE!!!
