I buy my headlinings from Aldridge trim UK , you may pay a bit more
But Quality and workmanship in the product is vital.
I had bought a headlining through ebay many years a ago from Victoria
and when I was fitting it , the seams were just pulling apart where it had been sewn
Then I had a local trimmer make one, he had 2 goes at it.
For me its Aldridge all the way,
I have fitted several for myself and my workshop customers.
