Embroidered J on 3 towels.
This kind of stitching is called crewel embroidery.
I used to do hand embroider and work for a co. that made masonic items. Co. closed in 2001.
This past year it was interesting to get invited by friend to a masonic installation. I had never been to one before or seen them in entire uniform and such. It was cool to see and know the work behind some of the items they wore.
