This is how I scent mine:
1/3
cup fixative
1/2 ounce fragrance oil
I put this in a zip lock baggie
and shake it up. I let it sit a few days before I add it to my potpourri. You will have to divide your potpourri
up into 2 bags so you can shake the fixative good into it. Pour half the fixative into each bag and shake gently.
Gently shake your bags daily for 1-2 weeks before you re-bag your potpourri to sell. If you're re-bagging
in bags, make sure you use polypropylene so it holds in the scent.
