I've often wondered why there isn't some resourceful natural perfumer 'out there' selling pre-blended accords as a whole product. Like violet, for example. Or gardenia. It can be done. I formulated a violet accord early last year, and it has finally stewed enough to be useful.
There are natural accord formularies for White Rose, Tea Rose, Moss Rose, Clove Pink, Sweet Pea ~ ah, sweet pea, for heaven's sake!
For a beginning natural perfumer, having these accords available would be a boon to their perfumery education. No to mention making some lucky alchemist a little bit wealthier. And if down the line the beginner becomes a pro and wishes to formulate their own accords, let them figure it out for themselves.
