It looks like you have some really nice quilts going there.
In each of the quilts, I am seeing three strong colors with white or a neutral in the blocks.
In the green/blue quilt, I think I would suspend the quilt in a two inch border of the lightest color before creating a pieced border of some aspect of the inside blocks ... little points or whatever ... that is really a very attractive quilt, there!
Good show! <wave>
I meant to say they are ALL very attractive. You do great work.
Lightest COLOR ... not the white ... and make sure the outside border is bigger than that inside border ... the little border says ... "The picture stops here" the outer border/s suggest ... the ice cream on the apple pie! (heated of course <g>)
