Having successfully carpeted several rooms I've decided to have a go at stairs. My main concern is hiding joins. The stairs has a 90 degree bend near the bottom. The stairs are very wide in the corner and I'm concerned that the carpet will be too bulky to fold neatly. So have decided to do these steps separately. I have read up how to do this and was going to hide the join under the nose by tacking the carpet and folding it up and over the nose to the step above. But now have read that the join can be hidden between the grippers at the base on the riser? Which is the correct way to do this ?
