All standard (cheap!) plastic easter eggs have holes in the tops and bottoms, making them perfect for threading into garland. I want to secretly decorate the night before, so all of the kids wake up to a festive house.
Easter Tradition: Have your kids plant jelly beans throughout the yard, then replace with suckers and lollipops after they go to bed. When they wake up in the morning, lollipops have "grown" where the jelly beans were planted. Such a cute idea!
