It took us almost 10 hours to do it but we got it hung!! We did it in our living room and it looks so wonderful. The reason it took so long for us is that we were having some trouble with get the angles cut right. We don't have some corners in our house that aren't 90 degree angles. For example our fireplace wall is at an angle to the rest of the room. For those that want to know....we had to miter the molding at 22 1/2 for those on the fireplace. A lot of trail and error. Can I tell you how happy, proud and exhausted we were when it was all done???? There are a few areas that need some caulking but for first timers we did a great job. I really need to take pictures and show you guys what we have done.
