Ha! There is no way that I am going to answer that question! It just depends on the look that you are trying to achieve. I did make a bead to show what the different looks are though.
For my test bead, I used a base of Effetre Light Sky Blue, and added large dots of Effetre Transparent Dark Aqua. On the “left” side of the bead, I marked it by making the end totally transparent. Then I added four stripes of Silvered Ivory Stringer, each using a different Ivory below the fine silver foil. The Ivories were: Effetre Dark Ivory, Effetre, Light Ivory, Vetrofond Dark Ivory, and Vetrofond Light Ivory. I placed them in alphabetical order from left to right, well, just because.
Notice that there are subtle (and not so subtle) differences between each of the stringers. Of course, these never look exactly the same, but this bead is typical. The most webbing is seen with the Effetre Dark Ivory and the least is with the Vetrofond Light Ivory.
Is this typical of what you other flameworkers see? How about jewelry makers – what is your favorite?
