Leather perfume

Today I've plunge into creating my new Leather perfume.
I'm fond of Birch Tar, and for me it's indispensable to leather. But leather with tar is very masculine and brutal - so, for variety's sake, I decide to make feminine leather.
Without tar...
but with...
black tea abs, orange blossom abs, immortelle abs, tuberose, labdanum, white cedar abs, castoreum, rose de may abs, kewda and cognac and so on.
I do love leather!
