Gudebrod makes HT Metallic thread in "A" and "D" sizes. The beauty of this thread besides the great colors is that it is as strong as its nylon thread counterparts. It can be used to wrap guides as well as ornamental/decorative.
They also make HT Braid. This is 1/8" wide and comes in 16 metallic colors.
Recently Gudebrod introduced Electra Metallic Hologram Braid. It is simular to the HT Braid but it also radiates light. You should see it in the sunlight!!!!! It is 1/8" wide and comes in 12 colors.
I use both Braids in my butt wrap design. My customers like it, I can do a wrap faster and I don't charge them extra for it.
I do not have to use color preserver but you can if you desire. It takes epoxy well.
Thanks for the info Capt. I'm going to try the braid on my next diamond wrap. My thought is to use two different colors offset by black thread to bring out the diamonds, the same way I would if i were wrapping one thread at a time. Am I on the right track? It seems to me I shoulg get the same result with a lot less work.
