Start with your 1st 4" ribbon and make a tail. It doesn't need to be too crazy long because I've got those waterfalls falling down.
Pinch that together and reeling your ribbon back for some slack and make a loop from back to front.
Pinch at center and twist and make another loop from back to front.
You'll have one loop pointing upward and one facing downward.
Next, add your next layer of your bow using your 2nd 4" ribbon.
Repeat the same process making slightly smaller loops.
Fluff out your bow, so that the loops lay diagonal from each other.
Secure with a zip tie.
Use another zip tie to secure bow to the grapevine.
Dovetail ribbon tails and work that wire for a nice curl.
