My first thought is to find some light blue lace and place it here and there. It is light blue, right? Gray? How about some white eyelet, here and there? White swirly fleece for the back?
Add some lace to any border you might use. There's always loads of 1-2 even 4 flat laces available.
ohhhhhhhhhhhhh, just thought, I've purchased some very feminine white on white snowflakes this season. Maybe a girly tonal for sashes or borders or blocks or binding?
