After scouring some catalogs, I found these jewelry storage ideas from Pottery Barn and the Container Store.
My 13 year old daughter could fill 2 of the storage chests- and by the way they are $349 each, Yikes!
As for the trees my house would look like a forest with all the trees we would need. Instead look around for some nontraditional solutions. We found this wrought iron rack and spray painted it a fun pink, and now all my necklaces are out where I can see them- Can you hear them screaming "Pick Me, Pick Me".
Ikea has the greatest little kitchen racks with hooks sold separately that you can add and add and add. This is rack is in my studio but imagine it painted turquoise and hanging in your room.
Caitlin Creer at CCInteriors found these fabulous bowls for me at ZGallerie for $19.95 and $7.95 and they easily fit my stacks of bracelets. Look around your cupboards for an unused salad bowl or deep serving tray. Or perhaps just an orphaned little saucer for all of your rings.
The important thing is that your jewelry is out where you can see it, and hear it calling to you "Hey pretty lady, I would look amazing with your creamy sweater".
