Blue canning jars are making a come back, so I dug around in the basement to find a box of them packed away since the 70's!!! They were once lined up on my kitchen counters with all kinds of goodies in them. These two are holding plastic and metal bottle caps and jar lids. Why you ask??? Since they are disposable anyway, I use them to hold paint for projects instead of using palette paper~~ sometimes you just need a dab of something and these fit the bill, then just toss them out!!!
