Here in Australia Halloween is not as big of a holiday as it is in the states (although it's slowly catching on). We don't celebrate Halloween, and like to focus on Thanksgiving. We hold a big Thanksgiving Dinner every year called "Give Thanks with the Yanks" and invite all our Aussie friends to a traditional Thanksgiving Dinner. I am planning to use these box-tracts as table decor for the kid's table this year. I know they'll love it! Plus we can't get orange pumpkins here so these are a great substitute!
Besides handing them out to trick-or-treators, you can also give them out to your Sunday School class, youth group, homeschool co-op, harvest party, and so on! Such a fun way to share the Gospel! Don't forget to add a piece of candy in the middle!
