Kallisto
I bet you love it..:) It's one of my very favourites, too!
As for blending it, try adding a drop or two of sweet orange. (It's the best perfume I've ever had - and I made it myself!) Lemon also CAN work well. For an "exotic" mix, try adding a drop of black pepper oil and a drop of orange; or you can try it with cloves.
Ultimately, it's all in the dosage: just a drop too much - or too little - will make a world of difference. But it's fun experimenting.
(Be careful, though: Ylang-ylang can give you a headache.)
