Hi again, definately would not of purchased materials to retrim myself. Winner products have the presses to make the door cards exactly the same with all embossing. A local trimmer would not of. If at all possible to purchase vinyl and houndstooth separately maybe do that for the seats only. But are they going to do an exact replica? I know i waited a long time for the material to be imported from the US to do the trimming but it was worth it. Hope this helps.
