Set the hay bale upright in a visible garden or yard spot where it will serve as the centerpiece.
Attach wooden boards to the top in a triangular shape to create a roof, painting them white for a clean, bright look.
Cut and paint wood trim to form windows and a door; fasten them directly to the bale using nails or staples.
Add small props like a wreath on the door and faux flowers in window boxes for charm.
Place a few pumpkins and a short picket fence in front of the display to frame your little house.
