So, I cut 3 strips of fabric about 8 inches long and used the pinking scissors on the edges.
Next change the stitch length on your sewing machine to the biggest it will go.
I always back stitch the beginning edge, but make sure the you don't back stitch the ending edge.
So once you stitch the whole length of the fabric without back stitching the ending edge, leave a couple of inches of string be for you cut it.
Next , start pulling the top string and pushing along the gathered material to the end of the cut fabric.
Once you got your desired gathered look, tie the open end into a knot and trim it.
Now you should have 3 gathered strips. You can do many things with these ruffly pieces.
Kind of looks like a bird :).
