It was probably the easiest thing I have ever done. (huge bonus!)
I found this roll of Burlap Garland at the Craft store. What luck...I had a 50% off coupon so it was only 4 bucks! GO ME!!!
I took out the middle string from the stitches and gently pulled to gather the garland.
It gathers really easily as long as you gently pull. I gathered the entire roll. I gathered half of it from one side and unrolled the other half and began again from the rolls end side. This made it easier.
Once the entire roll was gathered, I knotted the ends of the pulled burlap string to secure the ruffle. I cut a piece of foam core board in the size I needed and began to hot glue the burlap to the board.
Just keep on lightly gluing the burlap in overlapping circular layers until you get a nice center. I then took twine string, green lace, ribbon, and tulle and made a bow. It was super duper easy!
Now, I just have to do something about the smudges on the window! :]
