Aceca roof lining

[lew]

AE547 has no roof lining and is of the early type with wooden formers.My question is that I can see where the lining was tacked into the wood to hold it in place but how were the unsightly nail heads obscured. Could some one possibly post a pic of one so I could see the trick

I eventually found the tattly and torn original roof lining from my car. The solution is simple,the lining gets nailed in and then the lining is joined and folded back on its self to hide the nails
