For pretty much every Halloween of our marriage — even pre-kids — I have made these apple votives for the front porch. Easy to make. Easy to throw away (meaning nothing to store). Very inexpensive. I usually make them the day of Halloween and set them in a battered old metal tub on the porch (mix regular apples with votive apples). Added to the carved pumpkins and potted mums, they are lovely.
Lots of ways for kids to participate: fill the tub with water, pick out the apples, put the apples in the water, etc.
Because there is nothing particulary Halloweeny about them, I like these for any fall evening gathering. They make a simple greeting for a dinner party or even Thanksgiving.
Just watch out for flammable costumes. Find directions here.
