How does the gauge of the headpin coordinate with the size of the headpin?
Since the headpin is made of wire, it is measured in gauges. Common gauges for headpins range from 18-gauge (thick) to 26-gauge (thin). Choose the gauge that will go through the bead hole. For example, a freshwater pearl will have a small drill hole so you will likely need a 24- to 26-gauge headpin.
The size of the headpins relates to the linear measurement, or how long it is, and is usually sized in inches. Headpins come in 1/2 inch to 4 inches long. This variety of sizes accommodates short dangles to long dangles.
