This past Saturday I had the pleasure to attend a bed turning presentation by Marcia Kaylakie. See
http://texasquiltappraiser.com/ for more information about her.
She displayed and commented on quilts from her personal collection. She showed us one from around the turn of the century (not 2000) that had been machine quilted. I don't know how often people machine quilted in those days or how intricately, but it was interesting.
After her presentation we had "quilt roadshow" with Marcia dating, commenting on, and giving her opinion as to the range of prices individual vintage quilts we had brought in would bring in the current market.
