Hi Again ..... I`m just ` conscious` that the back-perimeter, where it meets your growing hair, will need to have the hair ` flowing ` forward because your own hair lies naturally in that direction [forward of your crown-point] and will be lying /combed over on top of your system...you`d need to have the system-hair tied-in in a ` forward` direction there ..... you could certainly mark / specify a particular area where you`d like the hair tied-in ` freestyle` but just for that immediate rear-perimeter edge it would be best to get the hair there lying in a definite forward style........ what you`ll do when time comes, is shave off the thin hair to the size of your system but you need to dampen the hair first and comb it / slick it back fully rather than the way it normally lies......that way you can then comb /brush what`s left, forward again onto / over the partial ! That will give you a seamless blend-in, where the system ` meets` your growing hair......
I don`t quite follow your other question about `moving` the system once attached ....you can maybe clarify that please..... regards for now .. Paul.
