Shaping tuiles take some practice! It may take a few tries to figure out the timing for perfect rolling. If you get frustrated, err on the side of under-baking. Put tuiles that still feel soft after they've cooled back in the oven to crisp. Place tuiles seam-side down on a rack and bake at 225°F for about 15 minutes. For best results, slide a dowel or wooden spoon handle into each tuile to maintain its shape.
