When it comes to carting home candy, children have a lot of options — plastic bags and containers, even noise-making plush handled pumpkins or cardboard carriers. But for moms and dads that want to save money and have their wee ones get more mileage out of their treat sacks, use pillowcases. They hold more trinkets and sweets than the other options and can be slipped under your tot's head to lull them to sleep.
