Apart from being a beautiful painting this is the draught, or coded instructions, required for a curtain made on the Nottingham lace curtain machine. A draughtsman would have painted it by hand following the original design drawn up by the designer. The draughtsman therefore had to be artistic and also know about the workings of the lace machine in order to translate the design into a workable pattern. This draught would then have been passed to the card puncher who would follow its instructions to produce the sets of jacquard cards needed to work the pattern on the lace machine. In general, red squares indicate back spool ties and green indicate Swiss ties, although there is no standard colour code and some manufacturers used different colours. This draught also has handwritten instructions along the length of the pattern describing among other things the width of the entire piece of lace (360 inches) and the type of lace (two gait Swiss). It also tells us that this is a 10 point lace which means that it is of medium fineness. I think these lace draughts are beautiful but the fact that they carry so much coded information makes them even more special.
