I feel like I'm going to go all 'Joan Crawford' on somebody every time I see a wedding idea with a mason jar.
They. Are. Everywhere.
Candle holders, pew decorations, lanterns, cookie cutters shaped like the famous 'Ball' logo, vases, invitations with the image embossed on them, used as glasses, turned into 'the theme of your wedding' snow globes, etc.
Mason jars are everywhere. There is not a thing wrong with these glass jars. People seem to love them and that's great.
But, if you don't want mason jars at your wedding, man, you are out of luck. Just look at Pinterest and you'll see what I mean.
