Here's some "research"
Not impressed? Whatever. As a child, I had a bff whose family was like my own and they collected this stuff. I've always envied it and marveled at the beautiful shards of frosty looking pastel glass. I've found smaller quantities of the stuff before and I usually just dump it in an apothecary jar and let it sit there. Maybe I'll try to make some art? I thought. Yeah, "art."
As you see, I patiently sat there and sorted out a bunch of it by color. I found an open frame with two sides that are lined with dark velvet for which to use my glue gun and stick glass to it.
Ooh, a skeletal hand reaching up from its grave!
Actually, it's supposed to be a white birch tree! See, it's got the branches and dirt on the ground? Shut up. For the other side of the frame, I really wanted something nautical because it is sea glass. I didn't even take a picture of the sailboat I attempted to create. Maybe a lighthouse?
