I guess this all depends on how you want the ribbons to animate if at all.
You can use a spline deformer, or use a cloth sim, or a sweep along a spline with a cloth tag to give it some thickness.
To animate you can use wind with the cloth sim, and a collider to force the ribbon to deform to the picture.
If its a still you could even sculpt it to get the exact kind of curls and shape you want.
Do you have a sketch of what it should look like?
