Aloha everyone from Hawaii. I am seeking any information people might have about restoring straw hats. I picked up a couple of woven lauhala hats (plaited from stripped pandanus leaves) about 40 years ago in Tahiti. They are still in good shape, but I worry about the fibers drying out and getting brittle. I've found lots of info/threads about cleaning and caring for straw hats but nothing about restoring pliability to old straw hats. My other question would be about the best way to put a sweatband in the hats. They were not expensive hats and didn't come with sweatbands.
