You will receive a 2 meter length of 100% natural silk with the needle attached. Yes, the thread has the needle attached. You did hear that right. This natural silk cord is grey. It's a steel grey which is a beautiful color to work with. I can just picture this grey thread with some natural grey pearls. The size is a number 6 which is perfect for most pearls. You will want the silk to be thick enough to fill the hole of your pearls adequately. We recommend the size #6 for that purpose. Please check out our how to video on knotting pearls in the A Grain of Sand Bead University.
