I created some candle holder for my wife. Ya'll know, happy wife = happy life :)
I bought these cheap aluminum insersts from Amazon to have a better feeling when putting candles in them. Please be careful and don burn your candles all the way down.
Let me know if you bought inserts wich don't fit. I will try to adjust the hole for your inserts.
These atre the ones I bought.
