How big are the beads holes?
That depends on the bead. Our metal beads have the largest holes. They are, for the most part, large enough to string twine or ribbon through. Some are large enough for leather or rubber cording. The next largest holes are the large Delica beads. Smaller, but still large, are the Czech pressed glass beads and shells. Next in line are the seed beads and Swarovski crystal beads. Opaque gemstone beads and freshwater pearls are next in line. The smallest holes are in the transparent gemstone beads. The holes are somewhat larger in the ones cut in China than those cut in India. These holes are so small, you may have trouble getting even a tiny brass twisted wire bead stringing needle through the hole. Plan on using a thin bead stringing material or wire for these beads. If you are new to bead stringing, you may want to start out with larger holes before tackling the tiny holes in transparent gemstone beads.
