Music Is My First Lovea Cross Stitch Pattern by Stoney Creek

I have just started this pattern and it is going to be beautiful when I get done, but that may be awhile. It is a huge design. The thing I don't care for most of all is it is on the front and back of the page. The other thing I am having trouble with is the gray area or shaded area of the chart does not match up from the left side to the right side of the chart. You have to be really paying attention or you will get yourself in a real mess. I have gotten off a little, but seem to be making corrections enough you can't see the mistakes. Am hoping it turns out as pretty as it looks.
