Since I still have time (and a clean sewing desk) I will still be playing with fabric, particularly the black and brights combinations.
Right now though -- I am pretty set on the monochromatic version. I tried to set up the pictures in the same way so Neutral on the bottom, Ice in the middle, and purple and pink on the top.
For Monochrome, I am using Black (neutral), Black and White (Ice), Gray (Purple), the White on White (Pink). The black neutral allows for small amounts of white print, the Black and White will have white backgrounds.
