What size silk thread should I use for knotting pearls?
To create the strongest strand of strung pearls, use the thickest thread that will fit through the holes in your pearls. Refer to the ''How big are the bead holes?'' chart for help in determining the hole size in your pearls. Refer to the chart, ''Types and Sizes of Bead Thread Stringing Material'' to help determine which thread will work best for the pearls you have.
