I have made enough for a little girl's quilt, and am auditioning how to set them.
Here they are lying on top of a bright turquoise hummingbird fabric. I think they get lost.
Here they are just butting up against each other with no fabric in between. Too busy.
If contrast is needed, how about black? I love the dramatic look of the bright blocks against the black, but don't want to use black for a little girl's quilt.
Black with the turquoise outer border? Maybe, with a less "in your face" black fabric, or a dark green or blue.
Still have not decided, so I contacted her grandmother to find out her favorite color and her bedroom color. But I have ordered the backing fabric, which has bright pastel birdies. I decided to go with flannel for the three kids' quilts I am constructing.
For two brothers, I have made lots more of the scrappy quilt blocks. This time I have added more darks, and I like them all set together with no sashing.
