I LOOOOOVED ng's Pineapple Orchid. Absolutely loved it!! Also, I just soaped Blue Hawaiian a couple days ago. I've had it for several months and absolutely loved the scent but wasn't sure how to soap it, plus I believe I read that it discolors. I ended up just soaping it uncolored to use for felting after it cures. So far the smell is wonderful and strong, and no discoloration yet. Behaved very well.
I wasn't extremely happy with ng's Orange Blossom. I bought it because my favorite perfume is a solid push up from Lush in Orange Blossom, but sadly ng's did not compare. It just wasn't as complex as I'd hoped it would be. My honey actually soaped it in his only made-it-by-himself batch and the scent did stick fairly well. I've been wanting to try BB's new Orange Blossom body safe candle FO too, but maybe it's just wishful thinking, hehe.
I'm not familiar with any of those RE fragrances sadly. The only Black Raspberry Vanilla I have used is from WSP and it faded to almost nothing pretty much immediately.
p.s. Rustic Escentuals sends amazing samples with their orders and are extremely friendly folks.
