I designed and shuttle tatted this pendant in 100% rayon viscose thread. Very silky threads is 3 ply, that is almost same thickness as DMC size 5.
There is a coral shell bead at the center and Swarovski beads add sparkle of a rosette lace pendant.
If I compare to cotton and the rayon threads;
Working with the rayon thread is almost the same as cotton thread, but the knots looks little bit loose, that's why you need to pull little hard.
Another thing is when you close a ring, you should be pull gently, because the rayon thread binds making it harder to close ring. It requires frequent unwinding in use.
In my opinion, very luscious colors rayon thread is good enough to make a beautiful and sturdy lace
