I created this necklace using No70 crochet thread, it is reasonably fine thread and creates a quite delicate look.
I have also covered the centre of the rose with a little "dome". The centre can be left open showing the cartwheel of spokes making up the flower or covered like this. I think that either look very pretty.
In this necklace tried out creating a vine leaf design, which is the leaf on the left side below and then added the Rose leaf on the right.
The cord is simply a row of crochet on the padding cord and fastened with a little iridescent flower button.
