I'm sorry if this sounds harsh, but that looks terrible Anubi5. The lace is sitting so far up off your skin that you can see the distinct shadow it is casting. Anyone you meet will instantly know you're wearing a piece if they see that hairline.

I'm not sure what's going wrong. The lace and knots look fine. It just seems not to be stuck to your head at all, like there is a millimetre gap between your scalp and the unit, and obviously the whole mesh is completely visible. I suppose it could be a problem with the fit of the piece, although there is no particular indication of that.
