When our power went out for four days, it necessitated a fridge cleaning. The entire top shelf was full of jars containing little bits of lots of stuff that we weren't going to finish. It was a blessing in disguise. However, we must have run the dishwasher eleventy-million times with jars. (Okay, maybe twice.)
I found these mummy jar votive holders on a lot of those "20 Easy Halloween Crafts" or "40 Easy to Make Halloween DIY Decor Ideas" that proliferate on Pinterest. Much harder to find the originator of this project. It's not rocket science though. It does give you the opportunity to use up the gauze that is becoming brittle in the first aid kit you keep under the sink in the bathroom.
Of course, now when I inevitably need gauze, I'm going to be going through the Halloween decorations looking for this!
