was a very fine French woolen dress goods fabric. In 1836, Jose Hofer of Mulhouse began weaving a fabric with a strong cotton warp and fine wool for the weft with a weight and hand similar to the 100% wool fabric. It was possible to print vibrant designs on this combination fabric using the steam style of printing. Delaines, as the fabrics were called in England and America, were especially popular for both clothing and decorating and are frequently found in woolen Log Cabin/Pineapple quilts of the late 19th century.
These are two images from one of my 19th century sample books. Both are wonderful Prussian blues prints. The title of the book is 'Delaines 1849'. I have reproduced these delaines on cotton with authenic scale and coloration.
