gardenpg, I used the 284Z when I made Santa of the Forest. His wooden staff had a great deal of this metallic thread in it. I also found it VERY difficult to use. It has now been "upgraded" to something softer and more pliable. The number is 284ZA. I have used it as well and with better success. If you go the "Told in a Garden" website, you will find a posting where it says basically: What is 284Z and what can replace it? I will admit...it is a very nice shade of gold.
