The Upholstery Forum

Good morning
I have been out of upholstery scene for many years,i decided to restore a 1968 karmann ghia and i have been looking for this (what i call fiber sew strip ) it is 3/8" wide and .090 thick black fiber/cardboard sewn into the bottom edge on the sides,folded over itself and pushed into a groove. The rest of the bottom perimeter has shark teeth. So i am looking where to purchase those fiber strips ???

I am tuning in on this and wonder what is out there for this too.

Something like this perhaps?

No he is looking for a carboard strip that has teeth on it like a saw. I have pulled it o older cars interiors just dont know the name of it.
