seat covers from PG classic

Seat skins in general... Very very few of the do it yourselfers pull the skins on as tight as they should be. Look over for sale listings at ebay, etc.., you'll see lots of loose wrinkled skins.
The true test is to first have the right tight fit then wait and see when the seams start coming apart.
As for who made them and where the quality of assembly and fit finish can come only from experience. When the panels aren't cut right and/or aren't sewed right, No amount of filler and labor would ever get all the wrinkles out. The hint or truth in advertising is found in the pics they provide whether the skin is laying on a table or on a seat. Example...

What you see is what you can expect.
Bottom line, Legendary Interiors doesn't have a true competitor in my opinion.
