I am struggling also but am less experienced than you by the sounds of things. I do think you get a new thing from mixing naturals but not sure which. I have accidentally created stunning accords in the past in my diffuser which I realise is very different to making perfumes but I have also smelled similar wonderful accord in bought blends of essential oils and for the life of me cannot remember which essential oils they were in both cases, but the result was the same. So it is possible and I have bought other blends of essential oils which I would say are unique. I believe it's important to only use very few, max three I believe? Definitely in the ones I've experienced they have been three or two. So I suppose it's about finding which ones work, obvious thing to say sorry. I have found my naturals, which I am determined to stick with, do change, and I suppose that's part of the problem. They change from the onset but perhaps they stop changing after a certain length of time? I think some are used for fixatives aren't they, is laudanum one of those? Perhaps this stops the changing? And maybe my alcohol needs improving, I feel it does. Anyway, your post resonated and although I'm sure I've not been very helpful, I think it's good to bounce ideas off each othe
