Aaaaaagghhhhh!!!! Crap!!!! I just cast a new medallion stand and the mold ripped! I did a makeshift repair though. Hopefully it'll hold out for a few more castings before I'll inevitably need to make a new mold.
In the meantime, I have 5 good castings on hand, 3 of which I'm painting right now as I type this. This is possible because I'm an ambidexterous octopus. Though I have to tell you it's quite the challenge casting and painting with tentacles.
