I started with a 19" zipper. I separated the zipper and using one side made one flower.
I cut my zipper into 6 2.5" pieces...leaving what was left for the center.
Next I ran my needle of thread through to make a gathering stitch:
I gathered the petal and looped it over it self and stitched it together:
I then stitched it to a scrap of felt: You could just hot glue it down as well.
Keep doing that 6 times.
I then gathered my piece for the center and wound that around and tacked it in. Covered it with a little gem and your set!
