I make homemade caramels for the family every year. The first year I made them, I was hold I was never going to be able to stop. So that's what the extended family gets every year. Oh, and friends too.
I also like the idea of a consumable. I like the seasoned salt idea, because it's not sweet. Most people do sweets for the holidays, and that would be something different. If you're concerned about the size of the gift, use some of the seasoned salt to make some popcorn or pretzel treats with it, and give a little bag of it along with the salt. Then people know what they're getting as well.
If you want more, inexpensive and FABULOUS ideas, try pinterest.com. Lots of great ideas on there, many of which I have done myself. For this holiday season, I am making tile coasters for a bunch of people. All it takes is tiles (sixteen cents apiece), scrapbook paper, mod podge and a little felt for the bottom. And they are gorgeous!
