I love it!!! What a great idea. I have given t a few little items for her sand tray shelves, that I've brought in to use in my trays and then decide to leave them there for others to use. Her favorite is a green heart-shaped bead made of glass. I've used it a couple times in sand trays. She's such a nut though I swear, one time I had a sand tray all in my mind before I went and made a little "tunnel" out of a toilet paper tube with one end taped off to use in it. Figuring, she can throw it away after right? A month later I noticed it's in one of the baskets on her shelves. Too funny!
