I have read the extensive thread on making sachets/potpourri with different things such as crushed corn cob, vermiculite, perlite, kitty litter, rock salt, etc. What did anyone find that worked? I tried 1 cup each of vermiculite, perlite and solar salt w/ 1oz fo. It doesn't look too pretty but smells great and is dry. Just curious to know what everyone thought about it.
