I have cast the troll and and the vain knight;) The mouldmaking was hard. I made a two part mould because I did not want to harm the sculpts and I had a bit of trouble with the bubbles but nothing I can't clean up.
I´m about to finish to more sculpts in 28mm. A warrior and a thief. I´m sculpting weapons to but I´m considering to sculpt some weapons in 3D instead and print them. I think I will be able to make some molds next weekend so that I can cast some miniatures.
