I don't know why this picture gave me the idea, but instead of a unity candle, horseshoes are good luck. Curtis, Adam and I can nail 3 different horseshoes onto a board and put it in our house. It represents unity and all three of us at the same time.
Use masking tape to put a strip of lace through the center of your mason jar. Then spray whatever color you like (white is my favorite) on your jar with the lace on. After that, let it dry and take the lace off. and put candle (or whatever you want in it)
