I get questions about how many pieces a person can successfully add to a flask for casting, and how close the pieces can be for casting.
This is a quick video explanation of how I would arrange several pieces in the same cast, as well as an explanation of why I arrange them like I do.
At the end, I added a montage of images and videos of how the pieces I cast were finished, and what they looked like when finished.
