In my recent attempts at molding and casting the Old Filthy MF and Jar patterns, there are currently four of each that I wouldn't be absolutely embarrassed to show other people. Here they are partially cleaned up on the belt sander.
These aren't absolutely terrible however I acknowledge I still have a long way to go.
And for those who I have shown these that say they like the imperfections in the surface and that it makes them look unique and weathered: Thank you, you are very kind. You are lying but thank you, you're very kind.
