You need Wire, for most things I use a 49 strand, clear coated stainless steel beading wire (but for tiny beads or pearls I use a 21 strand or fine coated beading wire). Wire snips, round nosed pliars, and flat needle nosed pliars.
a closed jump ring, clasp, pin for making a dangle, and 2 crimps (the tube shaped beads)
Begin by cutting about an 8 -12 " length of wire. Feed the end of the wire through the crimp, through the end of the clasp (notice that I removed the jump ring that was originally attached because it wasn't soldered), then back through the crimp
Pull it tight making a small loop, then smash the crimp with your needle nosed pliars
I then slide a bead on that has a hole big enough to hold both wires and cut the end of wire short enough to be hidden in the bead. Continue with your beads and spacers in whatever pattern you choose...
