It looks neat. www.flexistrand.com It's sorta like 2 weave tracks that are sewn together. You braid one track into your cornrow and let the other track hang down, for a tree braids type style. (though the website has a crawl that adamantly insists this is NOT tree braids, it just looks like a different way to do tree braids ) Have any of you ever used it? Pros/cons, tips, tricks etc?
