I have been trying for the past two months to get a good mold of a balloon, here are all the things I tried:

1. Two part silicone balloon made with smooth on 20 and 40, with a plaster and burlap mother mold
2. One part alginate mold with a plaster cast, so I can more easily make a two part silicone mold (this didn’t work because whatever I filled the balloon with wasn’t more dense than the alginate)
3. Two part plaster mold (I mean, you can tell why this wouldn’t work lmao).

Please, I’ve got intermediate mold making experience, but this has been one of the hardest molds I’ve ever made and I can only find one video on the internet about it and he does the first process and I just figure there’s a simpler way. Maybe there isn’t because of how a balloon deforms; its density and etc…

please someone give me some suggestions, I’ll try anything.
