OK, it's not exactly beach from property, but close. Here's another sea shell idea for those souvenir shells.
First, I took a regular (old) pottery pot, but I wanted it to have that aged look, so I put a little bit of white paint and a lot of water and brushed it on the pot. My brush was really wet. I just wanted a streaky glaze.
Once it dries, you can sand it down a bit, but I found mine worked out pretty well as is. I then just grabbed a hot glue gun and some shells that were relatively the same size. I glued them down, then took a bunch of smaller shells and glued them in the open spaces.
