I chose four sand dollars to mount to the board, two smaller and two larger.
My supplies - shadow box, matte board, sand dollars & epoxy (not pictured)
Mixing the epoxy.
I laid them out how I wanted them.
Then put the glue around the edges and wiped away the messes.
Here's my shadow box hanging in the bathroom.
Just so you know there's color in there, it's hanging across from this! On the counter is a photo I took in Exuma and shells we have collected from various Caribbean islands. I'm going to enlarge another photo I took and hang it to the right of the shadow box.
