everyone has their own method. U have to try different methods and see what works best for you. The way I do it personally. If i am attaching with tape lets say. I put the tape on the base of the unit, I leave the backing on , i dont peel it off. I only peel off the very back piece.. I put the unit on my head while making sure the back piece doesnt stick and I line it up where i want it. I tack down the back piece. than i lift up the unit in front of the mirror and than take off the backing of the next pair of tapes and tack that down.. lift it up undo the next pair of tapes going from back to front of course etc. this way I have a clear view of everything.. and than when i am finished with the base... I than draw in my hairline with a make up pencil or with the teeth of a comb. flip up the front, put in the glue or whatever.. and than tack it down. This method has worked well for me.

If i am using got2 b.. i just apply it on my head first .. on the base area.. put on the unit .. u have some time to get it right before it sticks.. than i attach the front the same way in the previous example.
