Okay John. Thanks. I guess Ilace wont be an option for dark colored people, as lace is bright and the dual lace will add to this brightness. I myself is very fair in tone, so I guess it won´t be an issue. One of the benefits that I sought to draw from the Ilace system, was in regard of the longevity of these systems if the knots was left unbleached. I lack to see the benefits from Ilace, except as an insurance to those who are so unfortunate to get purly bleached knots - I guess under such circumstances that Ilace will prevent such knots to show. However you would be paying your insurance premium with "added thickness". Is it correct, that if one where able to bleach the knots to white/translucent each time, this system wouldn´t be on high demand?
