I would second the granola and the bath stuff - in fact, you can make granola, put it in nice containers, give it away, and make bath stuff and give it away too.
If you grind oatmeal/put it in the food processor and mix in some vanilla/other essential oil, and a little neutral oil (like grapeseed/canola) it makes a lovely scrub. Just experiment to get your preferred consistency. Keeps rather well, too, but best kept in the fridge (but this makes it a really invigorating morning scrub).
