My wife makes soap as a side hobby and had some ideas for a new bath bomb mold. We’ve been paying people to do them, but decided we’d like to make them ourselves if possible to save some costs. Right now I’m stuck I feel like on step one. I’ve tried to project to surface but no luck. I’ve tried to emboss the sketch but failed at that as well as lofting (feel like lofting is the right choice but it comes out as a weird shape and not spherical). Are any of those the right option and I’m doing it wrong or is it a different process completely? Including pictures of past designs and the current step I finally gave up on until I try again.
