text: As I've always said if it's mushrooming slightly and every thing else is fine, then embrace it. As long as you've tested different wicks thoroughly and you've found one that works best plus checked it burns safely then all is good.
  
  There's no such thing as the perfect candle and we have to try to not get too hung up on this. Some of my candles mushroom slightly but the rest of the candle is fine. Some of my flames flicker, others don't but I think that's to do with slight drafts in our house.
  
  If you're bothered by it one thing I would say is to maybe take your oil percentage down to 7% or 8% and give that a try 😉
