Questions about this beautiful pattern
Hi!  I'm taken by this amazing pattern.  I have some questions: 1)are there places in the finished work that are left showing, if so what color they? 
2) if there is fabric showing I prefer to use linen over aida, what size fabric would I need to buy (28 count linen stitching over two threads. ) what color do you recommend? 
3) what information is included in the pattern?  
Thank you!
