I use a large breakfast-in-bed-tray to display the statement or larger necklaces.
The tray is by Indigo from Chapters.
One of my treasured piece is this vintage turquoise beaded necklace, passed down from my granny.
Umbra acrylic stand to hold more random necklaces. // White China basket from The Cross Design and Anthropologie brass holder (similar larger version here) to hold my bangles and cuffs. Squirrel box from The Cross Design to hold my rings // Antique brass and glass box from a home furnishing store in South Hampton (forgot the name) to hold all the other bracelets. And a couple of Hello Kitty dolls to make things interesting.
