I finished up the knitted/braided/woven paracord hatband. The hat is an XL and that meant an even longer length for the hatband. It's more like a rope than a band, as the braid/weave looks and feels like a 5/8 inch diameter rope.
The braided part is about 27 inches and I kept about a foot of length in the starting end strand and another foot at the finished working end. That makes the total amount of paracord used around 37 feet. I just tied it off in the back of the hat and it can easily be secured to the hat with a couple of small safety pins on either side, out of sight.
It could be made longer as a rope type belt, or shorter for various types/length lanyards. Just another way to 'be prepared'(former Boy Scout, so it's ingrained in the psyche), and having some paracord handy in case it might be needed for whatever. I didn't time it, but this is a time consuming project. The funny thing is that I could probably undo it in under a minute.
