Sew Many Bits

One of my favorite places to look for, drool over, and dream about high quality thimbles (no reproductions) is a British website called SewManyBits. They have pages for gold, silver/metal, enamel, steel-cored, English porcelain, other porcelain, and "other" thimbles, and books on thimbles and other sewing collectibles, plus catalogs from noted thimble and sewing collectible auctions. The owner also sells items on eBay, and has 100% positive feedback.
