Fair enough. I didn't "just" find Mason jars. As a matter of fact, I started using large-mouth Mason jars years ago after I purchased a vacuum sealer that had a jar attachment. With it, you could fill a large-mouthed Mason jar with anything (liquid, dry good, etc) and then suck all the air out, keeping the contents fresher, longer.
However, once I had a box of various sizes of Mason jars in the house, I managed to find a LOT of uses for them.
Besides the obvious - storage of food items - I use Mason jars for decorating (vases, tea light holders), storing non-food things (craft items, dog treats, seeds for the garden, nails/screws/washers), planting (terrarium, seed/plant starting), and sometimes even to eat or drink out of. Here's a great list of Mason jar ideas.
And my favorite Mason jar-related Friday Find is this:
|The "Cuppow" - why didn't I think of this??|
So, let's raise a Mason jar and toast the mind that came up with this brilliant idea.
