Blue Sky is the best.  From the first phone call to completion of the room – Ed was extremely professional and friendly.  He is tedious and takes the time  on the front end to ensure he goes into the project on install day fully prepared.  The paper we used was not a traditional or simple type, and there were some surprises on install day, however Ed and his wife got the job done beautifully in a timely manner.  They are perfectionists and stayed in constant communication as issues with our paper arose.  I would highly recommend Blue Sky for wallpaperhanging.
