Good idea?

I've been wondering what to do with these hemingray insulators that we got from Jarrett's grandma. She has hundreds of them. I may need to go back and get some with more color.

I bought a candle holder from a garage sale and put it in the fireplace and sat the old insulators on it. What do you think? I think it's fitting since Jarrett is an electrician. lol And it keeps me from having to buy candles for now. :D
