I also vote for sunflowers or other flowers - great background for them!

What if you used it as a back for a different quilt top?

I agree with appliquing some flowers or something on it. Also, quilting designs may perk it up.

I like it. I would go ahead and finish it and then add it to my give away pile for someone who likes blue.

Quilt it with a bright dark color like red or purple in circular or swirly designs?

I think it could use some red or orange

I think I would cut it into 4 and send the pattern going off into 4 different directions.

If it were me, I'd insert a 2" red border inside your outside border for a quick-fix and perhaps do your binding in the same red colour with a red backing fabric.

It s a gorgeous quilt and once quilted, it will look amazing!

I think it needs a border about 2 inchs wide before the wider print border. That should make it pop!

Applique something on it .. Sunflowers, bees, lady bugs etc.. Maybe that will change your mind.
