Thanks Meridith- it seems I have a knack for choosing the difficult ones-I also use the 9oz hex jars. I haven't had this happen much-rarely, but to have these few at once. Usually, for me, if the wicking is off, I know fairly quickly as most of the burn will be crappy....I'll try bumping up the wicking to see. Of course I could cut back on FO too and see if that helps the burn--of course I don't want to lose throw either.....I have quite a few scents that I have had no trouble wicking in those jars.....just keep on a going and they'll get there... Thanks again. Tracey
