Cloth stitched Windlace with a 1/2 inch foam core.
This windlace is used on cars from the 1930's all the way up to the 1960's.
Most 2 door sedan's take between 7 and 8 yards.
Most 4 door sedans take between 14 and 16 yards.
(A sedan is a car with a center post). If you have a 2 door or 4 door hardtop you should probably measure to see how much you need.
It is sold by the yard.
