Hi All,
For copper the right thickness 28 to 32 guage, find an old broken electrical appliance and split the plastic casing. There will be loads of copper wire twisted into a big strand. You have to unwind it but once that is over you have loads of copper wire for needles. You can also use unscented dental floss for thread. It is very, very strong and easy to work with, knot and all. This was passed on to me by another designer and the only reason I didn't share it ages ago was because I wasn't sure she would want me to. But she is using something else now so I feel it is okay.
What I still need is a thread no more than a 28 guage (very thin) but strong that doesn't need a needle. The doubling of thread means it sometimes will not go thru the beads with the tiny holes. The bane of most beaders. What is it that you use for the tiny bead holes, thread wise. Caitlin can you jump in here. I feel you might know if anyone will.
Pattye, I doubt brass will work. It will break more easily than copper. Maybe too hard for the job. Still you will find a use for it, such as using for threading designs before transferring to the thread.
