Cut a 1- to 2-foot tall strip of chicken wire long enough so it can wrap around the foam core tubing and overlap itself by about an inch. Do this for each tree.
Secure the wire to the foam tubing by first pulling it tight around the foam. Cut a few of the wire's honeycombs apart so that you have some loose wires, and twist them with the pliers around each other to hold the wire in place.
Cut the bottom of the chicken wire tube so that you can splay the wire out, and bend it into shape that resemble tree roots.
Cut a 3- to 4-foot tall strip of chicken wire long enough so it can wrap around the foam core tubing and overlap itself by about an inch and secure it to the top of the foam tube in the same way as the roots. This will become the leaves.
Cut the wire so that you can bend and twist it into the shape of branches.
Tear the butcher paper or paper bags into strips of varying lengths and sizes.
Mix three parts water with one part glue in the bucket, and stir until it is blended.
Dip the paper strips into the glue and water mixture until they are fully saturated, then run each strip of paper between two fingers to remove some of the moisture.
Cover all surfaces of the wire and foam tubing with the wet paper strips. Add three to four layers so that the texture is thick and your tree is sturdy.
Allow the tree to dry.
Spray paint the tree trunk and branches with brown spray paint if the butcher paper or paper bags have lost any of its color.
Wrap the branches with the fake leaves to the desired leaf density.
Place actual leaves or branches in the top of the tree to add extra density, texture and realism.
Spray paint any bare patches of leaves with green spray paint, if desired.
