I made a massive batch of tomato sauce yesterday, and, as usual, find that most of my plastic storage containers have disappeared, courtesy of my sons. I do have several quart size Ball jars though. Can I safely use them for freezing if I'm not going to go through the canning process? If so, how much room should I leave at the top?
You can use 'canning' jars ONLY if they are wide mouth. Otherwise no. If you use regular mouth jars, then as the contents expand during freezing, you will find the 'shoulders' of the jars cracked.

Here you go, a link directly to the Ball Canning Jars website where they list what is freezer safe and what is not. You can peruse their site for other information as well. Ball® Mason Jars - Canning Jars & Glass Jars

I do it all the time - small and pint size - wide mouth and regular. I do leave room for expansion.
Haven't had an explosion yet. Leftover tomato sauce is a favorite to freeze.
You mean you don't have a cupboard somewhere with about a hundred empty yogurt, sour cream and cottage cheese tubs and their lids, none of which match each other?

None. I recycle all that stuff. I had to go out and buy some Gladware today. My kids always take mine filled with leftovers when they come home for visits.

I think that's the difference between regular and wide mouth jars. The wide mouth ones are the straight sides. The quart sizes I have aren't.
You can freeze anywhere it's below the freezing point.
