I’m keen to make a 1m x 1m sandpit with a concrete floor like this one. Any ideas how to make the impression of dinosaur bones?
You just need a mould @kelli. I'd probably make them out of plaster, but you could also use concrete.
@kelli Nice little project!
Semantics but you should use cement/mortar rather than concrete so you don't have any aggregate in the mock-fossil. Will give you a smoother (and safer) finish.
Thanks @ProjectPete @I didn’t know there was a difference!!!! That is why this community is so great!!
