Hi everyone! Do any of you layer a tennis necklace with your 10 motifs? Or is this really bad idea in case of scratching? I am considering getting a short (like 15 inch) tennis necklace to sit above my 10 motif. Has anyone done this, did you like them together? Or if not, are there any necklace combinations you like with your 10 motifs or do you wear them alone always?
