I don't know what she's trying to say. Maybe just that she thinks it's a really old quilt design? I researched the game and found it goes back as far as the 12th century. Do you think there were quilts then?
I found a copy of a pattern for this block sold by The Progressive Farmer that they called Domino Net and one from The Ladies Art Co. called Domino.
The suggested colors for Domino Net were white and a dark print but it was suggested Domino be made from pink and white fabrics.
Blue and white were the colors the Chained Dominos quilt was originally made from according to Nancy Cabot. I decided to follow this idea when I made my 6" block. This is a very easy block to make. You need-10) 1 1/2" white squares, 6) 1 1/2" blue squares, 2) 2 1/2" white squares, 6) 1 1/2"X2 1/2" blue strips. The pieces are arranged like this-
I sewed my pieces together like shown below. The top left and lower right are made the same way and the top right and lower left are made the same. It goes together very easily.
