The first piece of wall sheathing in place. Getting it up wasn't too hard, since these side pieces only have to be trimmed in height, not width (4'). The main thing I learned while putting up this first piece was that marking the studs and any surface to which you plan to screw _before_ you apply adhesive is important. It's nerve wracking to have the adhesive getting tacky and dry while you try to find where to screw, other than on the edges.
