Candles in jelly jars, to me at least, mean young love.
My husband and I, before we were married, used to have dinner picnics on the floor of his apartment. I took very seriously, you see, that old adage about finding your way to a man's heart through his stomach. I'd spend half the day cooking at my parent's house and then I'd carry it all over to his place in a basket.
We'd spread a blanket on the floor and eat by the light of candles in jelly jars. I always wished that the moment wouldn't end... that I could stay, instead of having to go home.
These days jelly jars still mean young love... of a different sort. And they still find me wishing that a moment will never end...
