Green Music Altered Book Doodles

The first time I visited Emily's home to do some acting with her, so told me I could select a book from her stash to use as an altered book.  She had an old textbook on how to teach music - so being a music teacher - that's the one I chose.  It's been over a year since I started it, and I haven't finished all the pages yet - but I've only got 4-5 left to do.  I thought today I would post the mandalas and doodles that can be found within it's covers.
