are you planning on just turning the jewellery wire in so beads don't fall off? If so, selection of pliers b and q - £9.99
or using a soldering iron? I've never needed to use one in jewellery making
You can also use 'crimps' - tiny little silver tubes that you crush onto the wire so that it holds wire together - again, you use a selection of pliers for that.
The selection of pliers I'm talking about come in a black case with blue handles - I use the rounded ones for rolling the end of the silver (to make a tight 'eye') to hold beads on, the flat nosed ones for crushing, the sharp for cutting etc
