Bad upholstery purchase

Is that Upholstery or seat covers? if it is upholstery, it doesn't go over the old green vinyl. You have to remove the green vinyl and the new upholstery goes over the foam using a hog ring kit. It is also recommended to redo the seat tracks if needed and replace the seat foam. If it is a "seat cover" it is going to look like a cover, not replacement upholstery.
