It's a Gray Days DUCKs Treasury, at Etsy.com:
San Design from Etsy (Maman canard de la journée) made this beautiful Treasury and included one of my necklaces too! And here's a little picture of it, but don't let that stop you from going to visit the site. Just click the picture below or the DUCK name above and you will be spirited away, coming to rest in front of this great Treasury!
Just thought I would share something fun.
