Determine how long you want your runner to be.
Cut your ribbon just short of that length.
Use any wide ribbon for this project.
Fold your cut ribbon in half and mark it with a sharpie.
Glue a large leaf on the very edge.
Work your way to the right, gluing leaves on top of each other.
Vary the leaves as you go, and angle them for a natural look.
When you reach the mark, flip the ribbon over so that the bare end is on your left.
Repeat the same process of gluing leaves overlapping as your move to the right.
Add a couple of additional leaves in the center to finish off the runner.
