Your house must smell amazing! I need to stash some fragrant paper towels around, that's such a good idea! I would put them in my organza bags.I wipe out the small glass jar that I measure the FO or EO into with the paper towel, the bottle I turn upside down on top of a paper towel, which is in the small jar, and leave it for a couple of days.
(side note, I’ll sometimes put a bit of liquid oils into the bottle and shake it around, then let it drain, and use as massage oil. Yeah, I hate wasting any! )
