I did exactly what you said, and it worked out perfect! I even had a strip of White Monaco that, when stitched together with my WIP, looks almost like one piece.
Kiss Kiss Kiss!
I finally finished the pink outline, and after ten yards of Crescent Colours "Poppy" floss and crossing more "X's" than I care to count, for a total of 96 pink squares!
That is a lot of pink!
I present to you....Progress:
I am really enjoying this WIP, and cannot wait to start filling in all of those boxes.
