Ducky, that filament sounds really interesting...I've never heard of it. I got a notice today that my Razzle Dazzle has shipped, so I can't wait to try it out. It has a metallic thread in it so it should have a nice sheen. We'll see. If it doesn't work like I want it too, I'll be back at square 1. I have scads of the DMC 742 though and it looks great on Lesley's blocks.
