Fixatives for potpourri

[Poppy4lee]

Can anyone tell me what the best fixative is for potpourri? I don't mind what type it is i.e. powders, resins, gums etc. What I actually want to make is a sachet to put in the car. I've found that, 1) because the essential oils are so volatile and 2) because of the high temperatures that can be reach in the car (eg when parked in the sun) the fragrances soon fade. Any help would be MUCH appreciated.

Orris root is probably the most commonly used, although it's not particularly cheap. I think a lot would depend on which oils you are using and what solid/absorbent material you are using as a base.
