Hi Silver, I did as you say, and no that isn't the same technique. Lots of people try to copy Marc Petitjean's wings using that technique but it isn't how its done. Using that technique will result in a lower floating body.
The Petitjean technique is to trap the material in split thread and wind it over the thorax drawing it up and back in a doubling motion as you wind it. This results in the wings emerging from the side of the thorax rather than the top of it. The fly sits higher and is more stable on the water this way.
