Galadriel, Queen of Lothlorien

I wanted to ask you if I have the process correct in my head regarding making the closely guarded secret on NC and elsewhere of making the scenarios within glass objects! Now not for you to give me the prompts at all, just if this is how it's done. #1. make a single image of desired glass container (which in of itself is a challenge because they look like the things they put over a cake in a diner - don't know what they are called but intend to use a wine bottle anyway) #2. When a suitable one is saved, use as a starter image with a reasonable amount of weight but not noise and add prompt to set up the contents? or 1st glass bject must be on a suitable background in the 1st place so as not to ruin the intended final image #3 just go for it in one prompt which seems to not really work on my Dez trials so far lol? like do you make a new glass container for each intended final based on what the background was when the AI made the clear glass in the first place? TIA
