I finally found mirrors small enough to fit in your handbag / purse and having found them I have made hand embroidered felt cases to put them in.
This pink felt case has been decorated with a heart shaped group of flowers which have been finished with beads. The case measures 3 x 2.75 inches and although it is small it's big enough to hold a mirror in a plastic case and consists of a regular mirror and a magnifying mirror (both essential for checking hair and make up).
