I was imagining a whole grocery sack full of them.
I wonder how many "little ol' ladies" have empty canning jars sitting out in their garages somewhere? You'd want new lids/seals, but I'd think it'd be worth putting a shout out on Craigslist. Of course, I don't know how many grannies go to Craigslist, but maybe their grandkids do... lol
Another idea is to maybe ask around church nurseries and preschools for jars. Elementary schools. Little Leagues, etc.
I know there are several of the forum folk who don't have much money and need to be thinking outside the box for how they are going to do this healing program. I am ALWAYS thinking of economical ways to do things.
