French lace is thick- chances are high, that it just doesn't disappear. Next time order Swiss Lace (if you wanna go for lace).

I am wearing French lace (stock unit) right now and it lifts. That's normal; my second hairdresser said that is one of the reasons she doesn't sell laces.

And yes! You made a terrible mistake with your template by doing it YOURSELF. NEVER EVER do it yourself; a hairdresser always does it better (let's hope my hairdresser did it right; I will find out soon with my first custom unit...). Exceptions prove the rule, of course.
