Using a curling iron on fabric satin ribbon is there something you can use to keep the curl in the ribbon?

"You could try hairspray or fabric starch."

If you have a spray bottle - put in one cup cold water per 2 tsp of corn starch to make homemade starch. Or you can buy it. Hairspray works, but can get gummy. You can also soak in water, wind ribbon on a wood dowel and bake it at 200 degrees until its dry, they let sit until coool.

I have wound ribbon on wooden dowels dry, but them in the oven at 200 for 20 min or so, and let cool before removing. They keep their curl.
