We have 2 full rolls of tan craft ribbon - it is vintage.  The rolls are new and full, I couldn't even begin to guess how many yards, the rolls are about 5 1/4" across with the center hole being about 3/8" I would say at least 80 yards but most likely more.  The ribbon is acetate  rayon blend.  It is tan with a decorative edge on both sides.  This has the feel more of a sewing ribbon but was originally made for a craft ribbon (I aquired it with other craft ribbons).
