anyone of you guys know if its possible to add in recesion to a piece after its been cut in and how do you go about doing it
all your help will be appreciated
cheers

UK,
I wouldn't recommend it. The reason is that the hair line is graduated (there's only a handful of customers that specify a non-graduated hair line) and if you cut into it you're going to lose that graduation and it will not look natural. It's best to make a good template and have the factory follow that so the unit can have a realistic graduation at the hair line.
Regards,
John
