What gauge wire is used for headpins/eyepins when using Swarovski crystals?
The gauge of wire we recommend depends on whether you are finishing the headpin with a simple loop or a wrapped loop.
Choose a heavier gauge headpin when making a simple loop. To ensure the loop holds up to wear and tear, we recommend 0.028-inch 21-gauge headpins. They are a heavy gauge wire, but the crystals will fit fine.
