Trench Art Collectables from ebay
Besides decorating Shell Cases, there are various things made from them such as Match Box Holders, Ashtrays and more.
Even now, many shells, both live and used are finding there way to the surface.
Last week (April 2010) I visited the 'De Akkerwinde' Bed and Breakfast where my son and I stayed in 2009. I asked if anymore had come to the surface recently. They looked at me and said, as if it's a normal occurance, "Yes, some yesterday".
It is a normal occurance.
