I feel silly asking this, but what is the proper way to put on a DY bangle. DO you pull it apart or twist it? Please help. I don't want to ruin my new bracelet! Asking about both the Cable classics and the Petite Wheaton (one with hook). Also what is the proper fit of the Wheaton- the small is just right (no room to fit my finger through) and the medium has just enough room to fit my finger? TIA
