0.2mm (30 gauge)

Intricate work  such as weaving, coiling and embellishing.  Good for using with gemstones with smaller holes such as pearls when needing to use more than once.  Wrapping stones onto thicker wire or chain links.

0.4mm (28 gauge)

Use for twisting techniques, ie tiaras and hair combs.  Wrapping round beads and binding wires together.  Also good for coiling and weaving.

0.6mm (22 gauge)

Good for creating beading links and wrapping.  Use on Gizmo for coiling.

0.8mm (20 gauge)

Staple wire.  Use for creating rings, earring hooks, links, frames, spirals.  Can use with Gizmo, but it is harder to coil because of the  thickness.

1mm (18 gauge)

Good for frames, connectors, links and clasps.  Too thick for earring hooks, twising, coiling or binding.


Wire is also offered in different strengths, ie hard, half hard and soft.  This usually applies to sterling silver or gold vermeil. 

Hard - very sturdy but difficult to actually use
Half hard - strong but still malleable
Soft - very easy to use but not very strong or sturdy.

You can also work-harden wire by gently hammering with a rubber hammer or running fingers along it. (As you do when you straighten wire you are using it from a coil). The wire will naturally work-harden as you work it.


Pliers:  Round nose, flat nose, cutters (side or flush are good)
