Measure the chicken wire to cover each side of the flatbed. These pieces will eventually be used to make a drape around the flatbed (good for advertising your organization or your sponsors).
Fasten the chicken wire to the edge of the flatbed with nails or staple gun.
Step 3 - Float Base
Cut newspapers into 6" x 6" squares or into long strips.
Blend flour and water together to make paper mache material.
Dip newspaper pieces into paper mache and paste onto chicken wire in 2-3 layers.
Allow it to dry, then spray paint and decorate.
Step 4 - Stuff on the Float
Build the frame(s) of the objects(s) you want to be on the float (use wood, chicken wire, etc).
Attach chicken wire to "fill out" object or to add detail.
You can use cloth, paper mache, paint or streamers to decorate frame.
Make sure the frame is securely fastened to the base of the flatbed.
Step 5 - More stuff on the Float
Decorate and "fill out" the rest of the float. Fill it with spirited people.
Build a frame of an object or a design with wood, then elaborate using chicken wire. Use paper mache to cover the chicken wire, then spray paint or otherwise decorate the paper mache with your design or logos.
Use Streamers or chicken wire to decorate the edges of the flatbed.
Use balloons, but not too many. A balloon arch can look good.
Use original decorations (i.e., umbrellas, music, movement, etc.).
