I just starch/uses Stiffen Quik my twisteds. I only bake the korkers. The spray works well and I don't have to worry about weird polyester-plastic fumes in the house. I really don't know the cumulative effect of all of this ribbon cooking/burning! That's part of the reason I don't bake (except korkers).
