I have been using Bittercreek's wick stickums and have noticed that by the time the candle is finished burning, the stickum has disintegrated. Totally gone, like it burned away with the last vestiges of wax. Anyone else have this happen? I'm also using stickums from Candlemaker's store but I am not convinced these stay put all the time. At least it's still there at the end of the candle, whether it's in the right place or not... that's another story! Heard some advice on 3M heavy duty mounting. Maybe this is next for me?
