As you all know, I'm a big Hawaii fan, so my home office has a Hawaii theme. I have uli ulis, and an ipu on a shelf in my office.
So it was only natural for me to hang my ukuleles up there. I didn't want to use generic boring hangers, so I ordered some hand carved Hawaiian themed hangers.
For my small soprano, I have a honu turtle design. My Pineapple Sunday is, naturally, on a pineapple hanger. The Kamaka hangs on a whale hook, and my Kanile'a sits on a plumeria hanger. I ordered them from a Ukulele Underground member named Toucan Mango, and got them from his eBay store. http://stores.ebay.com/Toucanmango
I highly recommend them, as they feature great wood designs, and padded protection for your ukuleles.
