Museum of Printed Textiles, Mulhouse, 5/02/2012:

The textile museum in Mulhouse has also collected samples of all patterns developed in Mulhouse over the years. Small fabric swatches are arranged in books, by year and design. 

The second photograph shows the multiple wooden stamps responsible for the colors and detail of a single textile design. The wood was labeled by the number of the design (738, in this case) and by the order the stamps should be placed (A, B, C, …). Sometimes patterns would have over 10 stamps that would have to be placed exactly upon one another to create the overall image.
