Don't discard your failures
Leave them in the yard!
After a lifetime being a little obsessed by stone carvings, European cathedrals etc, about 10 years ago I got to visit Carrara, where *that* marble comes from. Saw contemporary craftspeople at work. Got home, angle grinder on a river rock. Mallet & chisels. Truly awful result.
So I dumped it in the yard.
Now with the benefit of time, I'm quite tempted to leave it near some sacred site so folks will think it's a *good* Etruscan artifact.
