So my centerpieces are lanterns. I put the correct size candle for what it says max 3 by 4 and it seems the lantern gets hot at the top to the touch, I even tried a smaller candle and it still gets pretty warm. Has anyone experienced this with their lanterns. My venue allows real flames so that's not an issue and the lanterns are meant for real flames just don't want anyone to touch it and get burned. Should I keep the real flame or use fake?
