Delaines

as the fabrics ( Mousseline de laine) were called in England and America, were popular for clothing and decorating.
In 1836, Jose Hofer of Mulhouse, France began weaving a combination fabric using a strong cotton warp and a very fine wool weft. It was possible to print designs on this 'blend' using the steam style of printing. This involved fixing the mordant ( hanging the mordant-printed fabric in a warm, moist room for several days) to the fabric before dyeing.

Two more designs from my antique sample book.
