Give it a go! I'd suggest you start with a plain piece of paper larger than a dollar bill to begin with though. The pattern is distracting and the pleats are quite small.
Start with something twice the size and see how you get on. Take your time, pause the video if you need to and fold accurately. As accurately as you can. If you fold the first one wrong, then the second fold will be up to the crease you just made and that will be wrong as well...
Take your time. Be patient. Pause and come back to it later if you need to. There are models on my site that took five or six attempts to make, each lasting three or four hours!
Let us know how you get on.
