Before doing any tricks with the actual loops, try doing them with ordinary thin rubber bands. This will at least give you an initial hunch on how to do it.
Other than that, like others said - practice slowly and carefull until you get the feeling for it. If it's of any comfort to you, I burned through my initial five Yigal Mesika's loops in about two hours, and through the other five in two days. It took me some time, but now a single loop can last an entire evening for me, and sometimes more than that. So it's just experience... backed with some ~30$ of loopy collateral damage on the way.
