Shell buttons add a natural beauty to your knitted garments. Abalone, mother of pearl, oyster, agoya and other shells are cut and polished into many shapes and sizes. Some simply reflect the natural character of the shell, while others are pierced, etched, dyed or rubberized. Small buttons, suitable for christening dresses or baby clothes, are cut into charming shapes such as hearts, flowers or animals. Use shell buttons on pieces that will be gently hand washed and treasured and they will last for years.
