@ edyle thank you for sharing your photo the visual will come in very handy. One question, do you trim the cotton as short as the silica wicks?

I used to experiment leaving the cotton wicks on the long side, but found no advantage; I trim them short now, but I don't make any effort to trim as short as possible so they probably look bigger than the silica wicks; certainly fluffier.
