Here is a necklace designed to echo the quaint image of birds resting of wires. It's shaped to rest at the base of your neck and pretty light and comfortable in strong and flexible plastic. When I was wearing it I kept forgetting it was there.
Though the plastic will flex to fit neck sizes somewhat larger than the neckalce is sized for I do also have it in different sizes. You can figure out which is best sized for you by measuring around the base of your neck with a measuring tape or a string. This one is the large size (for 15 in/38 cm) and there's also standard (for 14.5 in/37 cm) and small (for 14 in/35.5 cm). If you do need a size much larger than let me know because this one is pretty easy to size up.
