Cut leaves off trees and separate the leaves from the branches. Leave some of the acorns on the branch.
Remove any pests or galls. (see note below)
Open a wire coat hanger and use a pair of needle nose pliers to help hold the wire while you make a loop at one end and shape the rest of the wire into a circular shape.
Start threading the middle of the leaves onto the wire with the end that is not a loop. Make sure to thread them all the same way. Either face up or face down.
Once you have filled about 40-50% of the wire with leaves you can stop.
Bend the straight end of the wire circle and connect it to the loop end.
Fan out the leaves to fill the wire circle.
On the back of the leaves hot glue strips of brown paper to hold the leaves in place.
Then add more hot glue to the other side of the paper and glue the ring of leaves to a wire wreath form.
Add a bow to the top with floral wire.
Wire some acorn branches together with floral wire and attach them to the bow.
Glue a few additional acorns on top to hide the wires.
Hang and adjust the leaves as you like.
