From this tiny embroidered laundry mark I decided to chart the individual stitches for means of documentation and comparison. It was easier said than done because the entire group of motifs measures just 14mm in height and the tiny cross stitches are the smallest I have ever seen. It was difficult in some cases to see if it was one stitch or two, even when magnifying. Below is my best effort, which is as close as I think humanly possible.
The laundry mark is on the right-hand side of the shirt front, next to the side gusset. It comprises: at the top, a crown shaped motif, in the centre the letters A.F and at the bottom the numerals 36.
The embroidery is stitched with very fine thread and the back looks neat, although there are some trailing threads between motifs and areas of the design.
Later I will be comparing this laundry mark with other examples and I hope this will prove a very useful vein of research.
