British Grenadier Mitre Cap, 2nd Regiment of Foot, circa 1740 in Great Britain: Militaria: Badges, Uniforms & Equipment Posted March 23, 2017 I was wondering why the silk embroidery was done over cardboard cutouts, but then realised it is pretty obvious. The cardboard cutouts provide a stiff template and a standard pattern around which the embroiderer can wrap the thread. Without the card, the embroidery would either pull tight and pucker the wool fabric, or would not retain its shape. It must also have made it easier to standardise the embroidery patterns across the regiment by making dozens or hundreds of cardboard patterns when it was time to make a new run of caps. I have learned something about silk embroidery!
