Rosemary - To answer your questions:
- I make cables, but especially the last twisting can be loose. Just keep
in mind that a loose twist will come untwisted more easily, making putting
the end caps on a bit more difficult.
2.I make all of the bundles of 10 wires that I want to use, all twisted in
the same direction. Let's call this twist #1. Bundle a bunch of these and
reverse the twist direction for twist #2. The #2's can then be bundled and
then reverse the direction of twist again (so they will be twisted in the
same direction as twist #1). Call these twist #3. Continue to bundle,
reversing the twist each time, so that all odd-numbered twists go in the
same direction as twist #1 and all even-numbered twists to in the direction
of twist #2.
This way, you can make wires with thick strands of single colors, or thick
strands of mixed colors, depending in which bundle(s) a single-colored
smaller bundle or multi-colored smaller bundles are used. You really have
to play with this process to see what produces the effect you want.
The point in reversing the direction of twist is that you don't want to
re-twist a bundle in the same direction as the individual strands in a
bundle, as this will cause kinking. The kinking can be pretty, but the
edges are sharp and not usable for jewelry. If you know anything about how
yard is plied, the same rules apply. In general, you want every strand in
a bundle to be either an odd-numbered twist or an even-numbered twist;
avoid combining odd- and even-numbered twists in the same bundle.
I'll attach a drawing that shows this.
Search for 28- or 3-gauge stainless steel wire on Beadalon, Amazon or
many other beading sites.
Of course, you can also use wire other than round wire in the bundles to
create different effects. The possibilities are endless! Let me know if
you have any further questions.
