gold rope chain

That is just a line of interlocking split rings.

I've already finished one bracelet, the gold version. It is the one that I like most, it is very similar to the real gold rope chain! I've used metallic Sanbest thread, 4 strands, color gold, number 121. For the other two bracelets I'm tatting with metallic Sanbest, too.

Pattern is a line of split rings: 8ds/8ds. And that's all.

It is tatted with the third method that I showed here: https://ninettacaruso.blogspot.com/2016/06/interlocking-since-1869.html

... but in this case, I pull a loop of the shuttle1 thread (from front to back) through the previous two rings:

Then the loop is put around your hand, in the normal position to tat a split ring. The most important thing to remember is to leave the bare thread sufficient for "a playing space" (how do you call that?) between rings.

Ciao,

Another UPDATE: I updated the old post to add this note:  The "Interlocking Split Rings" as an element in tatting was first introduced by Mrs Ruth Perry, in 1998 (different method but same result, two lines of split rings tatted at the same time, no bare thread between split rings).
