How do I decorate a mirror with sea shells?

These happen to be mussel shells but any kind and any design would work. These affixed with Elmers. Mirror in use at least 20 years.

Add a wood backing the mirror will sit center with the amount of frame you want to place the shells. Hot glue them on. Mirror will be heavy so make sure you use the right hangers to hang up.

Hi Teresa, this video has a nice mirror style

I would suggest using E-6000 to glue on the shelves in the decorative manner.

Its at walmart and craft stores-

Ive used it to flatten glass marbles and faceted glass plates on wooden glass windows to make decorative hangings.

Please have a look at product information to see if it might meet your needs.
