Interior Walls: Wallpaper Liner

My interior has been sitting with an unevenly primed OSB surface for quite some time now.  Not the most gorgeous wall finish... but it wasn't finished; it was waiting. Waiting for the loft floors to be fastened down, waiting for the ceiling panels to go up, waiting for all manner of tasks along the way to be completed.

Now, after a whopping two days' hard labor (sarcasm--I hardly accomplish anything in two days anymore), the wait is over! Check out that much-smoother-than-OSB surface!
