Everyone here has some great tips!
I have canned tomatoes, grape juice, beets, and apple slices using the hot water bath method.
A friend told me green veggies need to be canned using a pressure cooker -- I am afraid of them, so I never tried it. We froze our green beans, etc. and used them over the winter. true: as already said, canning is best, due to any power outages.
I NEVER reuse lids - I have a cow checking mine over and over again to make certain nothing spoils. I have never tried the BPA free stuff, but I'll look into it.
Thanks all.
