3 Brass hinges
Life-size coffins can be made out of cardboard or styrofoam boards. Coffins are popular Halloween decorations. They are used for Halloween parties and in haunted houses. Life-size coffins can hold realistic dummies for a funeral home scene, skeletons or real actors in costumes that pop up to scare people as they pass. The classic coffin shape is called a toe-pincher. You can make your own life-size coffin without wood for a fun Halloween decoration.
Measure and cut out the panels of the coffin. Measure and cut two 1-foot by 1-foot squares for the head and foot of the coffin. Measure and cut out two 16-inch by 1-foot shoulder side panels. Measure and cut two 56-inch by 1-foot side panels.
Video of the Day
Measure and draw on the cardboard or styrofoam board a line that is 1-foot long. From the ends of the line draw a 16-inch line that is at a 45-degree angle from the 1-foot line. From the top of the angled 16-inch lines on both sides, draw a straight 56-inch line. Draw a 1-foot line for the foot of the coffin that connects the ends of the 56-inch line. Cut out two panels at these measurements to create the bottom and lid of the coffin.
Tape the 16-inch side panels to the 16-inch sides of the bottom panel with duct tape. Tape the 56-inch side panels to the bottom panel with duct tape. Tape the head and foot panels to the bottom panel. Tape the long side of the lid to the side of the coffin frame with duct tape. The tape is sturdy enough to be used as a makeshift hinge for the lid.
Paint the cardboard or foam coffin with brown paint. Make concentric circular lines along to panels of the coffin to make it look like wood. You also can paint the entire coffin black, if desired.
Tape brass hinges along the top of the makeshift hinged side of the lid by making circles with the duct tape and placing them under the mounting plates of the hinges.
