I'm sure you could google images for home canning and get plenty of pictures for Dad.
I did several cases of green beans this year, and some kale/collards/chard, and some spagetti meat sauce. I have limited area for storage so can't go whole-hog. As well, I'm the only one that takes care of the garden, snaps beans, and does anything else involved. I do what I feel like doing and not much more.
I have done my own saurkraut and then canned it. It was awesome. Then there were the peaches in honey syrup, peach butter, pickled okra, tomato sauce, peeled tomatos, and some other things I can't quite remember what they were.
When I first started canning I remember what a comforting sound it is to hear the jiggler on top of the canner making noise in the kitchen. It dragged my memory straight back to Grandma's house when I was a young boy, watching all the old Aunts sitting on the front porch snapping beans and yakking it up. Grandma and Grandpa's gardens were always good for a fussing at if you got caught running through them. It was a riot to look at the separate piles of tomatoes in the kitchen from the garden of each to see what the running tally was and who had the biggest tomato. Never was a word said about the contest, but everyone knew the score.
