When it comes to organizing bracelets, a good option for those who like to have things put away out-of-sight, is to dedicate a portion of a drawer to them and use organizers to keep things separated and neat. Clear ones always look nice. Remember to measure before buying!
For those who are more visually oriented (right-brained!) and prefer to have things out, trays are great for corralling pieces and keeping surfaces from looking like a cluttered mess.
Another option is to hang them on a jewelry tree, which makes for a lovely display.
Last but not least, a fun idea is to keep them in pretty vintage cups. Look for ones with a wide enough mouth to fit the width of your pieces.
