Well, it really isn’t rocket science. Unlike knots in some ropes, these knots usually hold remarkably well. Just have scissors and maybe a knife readily available. Under tension, strips of bedsheets cut like butter, much easier than most rope. The downside is that they don’t cut well when not under tension, and the knots (while they can be undone) take a bit of effort to loosen–long fingernails help.
I like the feel–soft but very strong, and not as stretchy as some rope. You can also choose your own widths. And they look great!
