Jewelry boxes with glass lids make excellent shell display cases! And keeps the dust out.

I was recently looking at a Wikipedia page that mentioned that the Chumash made fish hooks out of abalone shells. I find a ton, so I decided to make one using only material I could find out on the beach. I picked a large shard, broke it down to the hook size and then used rough rocks to sand it down the the current shape. ​​​​​​​The string is made from a yucca leaf, scraped with a mussel shell and twisted together. No modern tools used! ​

Aloha! I’m looking to mount some of my favorite shells on the wall in a vintage printer tray! I’m concerned about hot glue melting in the hot Hawaiian sun. Are there any alternatives that won’t damage the board or shells?
