That is a multicoloured Sanbest thread, it looks completely different on the spool, so I'm very happy with the result.
My pattern up there mixes double stitches and treble tatting stitches and the section with trebles is a chain, with the under-over effect that makes it look like rings. I used the same effect in the snowflake with the ice-drop in the centre (here: https://ninettacaruso.blogspot.com/2020/01/shine-light-on-tds.html)
I'm enjoying playing with this metallic Sanbest thread, these are other things I tatted with it:
That is a module, pattern is by Eva Antonucci.
Those bracelets are just lines of split rings, beads are preloaded in both shuttles. Pattern is a repetition of split rings tatted in this way: move 5 beads in the loop around your hand, then tat 6tds with beads in between (move from the hand), then the other side is 8ds, very small picot, 3ds. Close it, letting the two last ds and tds stitches very close to each other, then, when it's closed, the core thread is near to the very small picot. To continue, lock join the core thread to the small picot, reverse work, switch shuttles and go on with the next split ring.
If you share any of my patterns, please put a link to this blog, don't copy and past pictures. I hope you understand, thank you in advance.
