Thimbles became popular in mid 1800 as a result of the special thimbles that were made for the Great Exhibition held in the Crystal Palace in Hyde Park, London. The earliest known thimble was Roman and found at Pompeii, made of bronze. You can find them in many colors. They were made from metal, leather, rubber, wood, glass, or china. Early thimbles were sometimes constructed from whale bone, horn, or ivory. Enjoy the hunt.
