Just saw this thread today, so if your curious I use 100% soy and i use htp 31 wicks (called tealight wicks) from southern scentsations, so far it has worked with every scent I use and I cant keep tealights in stock. this combo ,for me, gives off a a great scent throw. I use some of her oils too. Check em out if your still having a problem , great customer service. I hated tealights before using that combo and now its the easiest I make..thought Id share my findings :rolleyes2hth
