I`ve taken a pic off your other thread ..I`m not so sure you need any flaps as such.. it seems like you`re trying to bring your temples out to a `point` on the side of the forehead.... if that is indeed where your hair used to be, well then you could go for it but be aware that it could prove `fiddly` from the point of view of the practicality of attachment..... it will also have to be made in French lace there, as Swiss would not withstand the `pressure` of detachments for too long..it would tend to fray and tear.... a `thin` island /strip of lace like that could prove problematic from that practical issue.....make your best judgement on it ....obviously you can see better than I can, on what needs replacing....... I`ve marked with a yellow circle what I`m talking about....the red line is a suggestion and it has less `obvious` flaps.... I`m not saying to totally change your idea, but just making you aware of the practical issues with getting a system with `odd`shaped flaps like that.... it CAN be done , but may prove `fiddly`.
