the donuts are cool, but seems like a lot of time to braid up something that will get unbraided to use later.
a paracord belt or sling is the kind of thing you don't want to unbraid just because you need "a little cord". no problem undoing it in an emergency, but wouldn't wnat to do that once a month.
i'm a fan of a "cord kit" with some pre-cut sections with melted ends in common lengths. say 2' or 3' and 6' lengths for the mundane day to day stuff. this should help keep you from chopping up the long length for every little use. saves melting ends evey time you cut a length, etc.
bundle it up and a ranger band around the bundle doesn't hurt.
