We purchased three headstones to mark where the ashes of our previous fur family were buried. They deteriorated within 6 months so we decided not to take another chance on buying them and made them ourselves. We have a store in Alamosa that sells pavers and sand and gravel. I went there to see if they had any that would make good headstones and voila they did. I bought 6, three for our deceased fur companions and three for our existing fur family.
I sealed them with clear exterior boat varnish, then stenciled their names on each, picked a photo of them when they were younger and glued it to the stone. Then put 1/4" clear Plexiglas on top sealed with exterior caulk. The irony is that all six of these headstones cost less than one of the purchased ones and are far superior.
