There are a few simple principles to keep in mind, however, whether you decide to use glass or gemstone beads. Color choice is subjective. When choosing colors, keep in mind what you will wear with your jewelry. For this reason, I make multi-colored chokers that go with everything. Texture is the feel your choker has with the use of various shapes and sizes of beads.
Different shapes are round, barrel, rice, star, heart, tube, swirl, chip, oval and chevron.
A lot of variety will yield a very textured piece of jewelry. You can achieve a smooth texture with similarly shaped and sized beads. The size of your choker must be in proportion to the wearer. If the woman is petite, smaller beads should be used. If the choker is for a big woman, she would look better in larger beads, or several strands of small beads.
