Maybe I'm just lazy, but the idea of all those dangles... I used to shudder at the thought. Not because I don't have the patience to sit and wire wrap. I love wire wrapping! But when I first thought of doing clusters, the process of making one dangle, attaching it to the piece, make another dangle, attatch it to the piece... rinse, repeat... that's what made me run!
I work in an assembly line style when doing clusters, now.
1) Estimate how many beads you want for your cluster and slip each of them onto their head pins. Try not to overestimate so we don't waste any head pins (I forgot to take a picture of this step).
2) Take your chain-nose/flat-nose pliers and bend each of the head pins at right angles near the bead. Notice, this is the first step to making a loop.
3) Grab your round-nose pliers and make all your loops. In the picture above, I made wrapped loops.
4) Snip the excess wire for all your dangles.
5) Tuck the pointy bit into the wrap (again, forgot to take picture).
If you notice, each step has it's own pair of pliers associated with it... except the first step, which requires no pliers. Because you're not constantly setting down and picking up a new pair of pliers, it cuts down on the time it takes to make the dangles.
If the cluster looked thin, I could always attach more. But if it was too full, I'd have to take the dangle off and kill the head pin which always seems like such a waste.
Another idea for clusters is to string them onto a head pin like in these earrings below:
I also love the look a strung cluster of dangles. Or clusters on a chain! When I make chained clusters, I make simple loops instead of wrapped and it's still rather beautiful.
Hope these tips help you when making clusters! Please don't hesitate to ask me questions! I'll answer them if I can :)
