For something a little different, these slipcovers have a flat flange welting instead of the traditional welting. It is made exactly the same way, except there is no cording inside, it is just ironed flat. It gives the furniture a more contemporary look. The only thing I don't like about it is, because there is no cording inside the welting, the stability that the welting normally gives to the cushions and the base of the slipcover isn't there. It really isn't an issue since there are plenty of cushions that don't have any welting at all. What is boils down to is personal preference. And the look you are going for with your slipcovers.
