According to Wikipedia, "May Day was celebrated by some early European settlers of the American continent. In some parts of the United States, May Baskets are made. These are small baskets usually filled with flowers or treats and left at someone's doorstep. The giver rings the bell and runs away. The person receiving the basket tries to catch the fleeing giver. If they catch the person, a kiss is exchanged." When we first moved into our neighborhood, the kids and I thought it would be fun to make May Day baskets and put them on our neighbor's door knobs. These made quite an impression! Our neighbor's loved them, so we have continued the tradition every May since then. They never have rung the door bell, but have quietly placed the May Day basket on the door knob, then they run away so they won't be caught.
This year, I looked through Pinterest for some May Day basket ideas. We saw a couple of ideas that would work, but adapted them for what we had on hand.
