Glittery glue dots - It looks like those glass filler stones (or maybe dried resin or glue? hmmm), E-6000 and glitter for the materials - No instructions, but it seems pretty simple going from the pictures. :)
I'm a teacher's aide, and the kindergarten teacher had the kids make these for my birthday. They were just beautiful in a variety of pastel colors and they are still sitting on top of my refrigerator in a basket.
