Ferrari FF - starlight headliner

Hi fellow FFers - I am considering adding some fine starlighting to the leather headliner (I am without roof - not missed at all As i am a strictly a front seat driver)... any opinions on this? I have messaged Khans for a quote but happy to consider other reputable specialists...prefer south of country (London way) so I can drop off/ pick up but that's not an issue if there is a solid recommend who has worked on similar projects. Not sure how the quality of the lighting / finishing varies as yet...don't fancy fibre sticking out of leather so needs to be clean/ flush/ a night sky not a price based on number of lights but based on the art and finesse. Help?
