These sturdy thread cards are beautifully designed and are of excellent quality with the graphics printed on both sides.
They are similar to those used in the 19th century for wrapping linen thread in Normandy, France. This thread card motif, CB, is taken from a geometric design dating from the early 19th century. In the middle, the two letters "C" and "B" are the Frédérique Crestin-Billet family name, a.k.a. "Madame Sajou".
