Restorative buttons

After many months of searching at thrift stores for buttons and coming up relatively empty, I had a restorative experience yesterday!  As in, it restored my faith that it was possible to find beautiful buttons in thrift stores.

I found these at the bottom of a bin at our Goodwill Outlet.  The sparkly ones were mixed in with some Christmas ornaments -- not even vintage ornaments.

 The larger stones on the outside are aurora borealis stones; the smaller ones have a pale green tinge.

Here's what the back looks like.  I think they are just beautiful!

I believe these grape cluster buttons are made from Lucite or a similar plastic with sparkles in the mix.  They definitely need to be cleaned but I have to research the best way before I attempt it.

Aren't they fun?
