Door Greeter Let’s start by building a strong cardboard arm from which we will hang our door greeter. The door greeter will rise as the door opens and fall as it closes. Cut two 3”x8” pieces of chip board and then cut to the length of the coffee stirrer sticks. www.build-it-yourself.com
Door Greeter We’ll strengthen the cardboard by taping wooden coffee stirrer sticks to the cardboard. www.build-it-yourself.com
Door Greeter Tape the two pieces together. The tape should act like a hinge so you can fold the pieces in the next step. Punch 2 holes through which you will thread the string that makes your critter go up and down. www.build-it-yourself.com
Door Greeter Use one of the small 1.5”x3” pieces you cut off in the 1st step. Tape it to the two legs to make a triangle. Triangles make strong structures! www.build-it-yourself.com
Door Greeter Now you need to make a critter. Make it as light as possible. Perhaps a cuckoo bird made from foam rubber, foamies, sponge and pipe cleaners. Some ideas are posted here. http://www.build-it-yourself.com/project-lab-setup/proj-lab-setup-greeter.html www.build-it-yourself.com
Door Greeter You’ll need 2 push pins to attach the cardboard arm to the wood frame surrounding the door. Bend a paper clip to form an ‘S’ shape. This will allow you to quickly hook different critters to greet visitors. Cut a 6 foot length of string or thread. www.build-it-yourself.com
Door Greeter Tape one end of the string to the edge of the door. Thread the string through the punched holes in the cardboard arm. Hook up your critter. www.build-it-yourself.com
Door Greeter When you open the door, your assistant will greet visitors. You could make the critter hold a sign or dangle some bells. www.build-it-yourself.com
