use plaster bandages ( the one used by doctors to make plaster casts ) they work great. When i was an architecture student we used to make light weight sculptures using this technique. They are very easy to use and the fabric inside makes it stiff and break resistant. a bit more expensive though .
Back in the mid 80’s some guys wanted make a replica of the Lamborghini Countach the story I heard goes something along the lines of the guyshired one for a few days and set to making molds of the panels. Needles to say the limited time resulted in not fully cured molds which “sagged” somewhat - but they pressed on many ill fitting fiberglass panels were made. The point is your in good company and as frustrating as failure is if everything worked we would never learn anything.
