Some of the comments I have read indicate a problem with
keeping the wire pliable, For those who are familiar with
annealing, that is the solution. For those who have not used a
torch or kiln while working metal, this is a technique that will
assist you in your final goal.
Another suggestion I would make is to use fine silver wire instead
of sterling, since it doesn't work harden as much, which means you
can do a lot more weaving without annealing (if, of course, you are
Thin-gauge copper wire is good to practice with as well, and comes
in a lot of colors that can be incorporated into designs. I've used
26-32 gauge colored copper for weaving, knitting and crocheting and
not had problems with it work hardening or breaking.
Gold and sterling silver, on the other hand, work harden pretty
quickly in my experience, so they are not ideal for weaving unless
you have a torch set up for annealing. Sterling will break if it is
bent too many times without annealing. I know that a lot of wire
jewelry makers don't have torches, since so many styles of wire-work
can be done without soldering, so the type of metal as well as the
gauge can be an important consideration for weaving. I wouldn't say
that any kind of metal is impossible to use, but some are definitely
easier than others.
