I followed this tutorial, used a border like this doll quilt, and used this quilt as the inspiration for the treatment of the circle in the center (it's done, in my case, by applique of a blue-dot circle and then cutting out a square of the white fabric barely larger than the blue circle, folding it into quarters, cutting a curve out of the corner, and applique-ing the shape on top of the circle). It's not perfect but I like to just chalk that up to "handmade".
All that's left to do is to add solid-blue squares to the corners (I can't seem to find what's left of my solid blue fabric. . .), put on the back (which will be blue-green, rather like the color in that Denyse Schmidt square print there), and then bind it all with the white-with-aqua-dots fabric which is kind of out of focus but toward the top of the photo above. And then quilting. Which will be pretty minimal on this small of a quilt. Sadly. I do enjoy quilting.
