Thank you all for the suggestions for filling my Halloween/Fall jars. When I was in the dollar store, I also found a bag of those big, orange cheese puffs. Perfect for something at least vaguely "Halloween-y." Of course, those are something I WOULD eat, except I wouldn't eat them when I first got them into a jar, and by the time I'd be tempted, they'd be pretty stale, so it seemed like something I could take a chance on. I was also at Trader Joe's and found a couple bags of inexpensive sunflower seeds that were darker than average--another good option. Of course, I also purchased a few of the things you all suggested, and my friend Missy suggested black beans, so I have those too. Now I just need to find time to fill those jars!
In the meantime, Susan sent me a photo of her scrappy project to share:
Nice, Susan! Thanks for sharing.
