I love it just the way it is! As others have suggested, the quilting will add to it's beauty. Often, I've thought a border on one of my quilts was kind of bland, but when I add a nice contrasting binding, it perks right up.
It's a really cute quilt and a great way to use up small but not too small pieces of fabric. The little boy will love this quilt all the way to tatters! And that is a good thing.
