Dark, slightly dusty navy broderie anglaise trim, about 78mm wide in total, with the embroidered part measuring 43mm tall from the lowest point to the highest point of the design. Embroidery is slightly darker than the base fabric, which is very smooth and similar to a 70gsm or so cotton voile. Trim has a wrong and right side (see photo), but looks quite neat from either side.
These cotton trims are used to add detail to clothing or for edging cushions and accessories, etc. There are some loose threads and/or extra fabric which you may want to tidy up yourself with small scissors.
