I'm in a different group, but if you don't mind my 2 cents worth:
I went back and looked on pg. 31 at Elle's top. Elle's center has a softness to it, with the gentleness of the tree branch and flowers. The checkerboard seems too rigid and from the EQ6 picture, IMO, makes the center recede too much - like you're looking at it far off through a window. The black border with floral applique brings the center right out. I really like the patterns you posted, Pam. They look like they'd have the same elegant movement that the center does and would be very complimentary.
