Question for you thin skin wearers: I've been thinking a lot about trying a thin skin piece, and this thread has been more than helpful. With lace units I have the HARDEST time getting the piece attached without bubbles and waves. If I get the front hairline flat after tons of work, the perimeter will ALWAYS have a bubble. If anyone were to even LIGHTLY brush their hand through my hair a finger would go right through it to my bare scalp. If thin skin isn't made to perfectly contour your scalp, is it hard to stick it on without wrinkles, bubbles, and waves? And quickly, you say the front hairline can have a visible line, how visible are we talkin? Thanks!
