I don't think I have found that 1 yet. I have liked to many, but have always wanted to tweak them with different scents. I did however have the "aha" moment with my lotion. After finishing the lotion and letting it cool and all, I opened it - I immediately loved the smell - you can say I am a little addicted to it at this point. And when I rubbed it in it just seemed more perfect. When I dug into it again, I just knew I still loved it as much. I wasn't sure if I could recreate the recipe - I had written it down, but was still uneasy because I hadn't recreated any other product - none I liked wholly and fully enough not to tweak the second time around. But I did recreate it - a little thicker - but that was alright. Since then I have made tons more - given it away, offered it to co-workers - all kinds of things. And no one had anything bad to say about it, and they all wanted more of it - so it became my "signature" lotion. And I still love it - everytime I open it, its like relaxation in a bottle. I think that when you found your "signature" product - you know... you have no qualms with it, and you want to recreate it exactly how it is. If you want to tweak it - it probably isn't going to be your "signature" anything. Thats just my two cents - hopefully it helps.
