I agree with Jackie...sometimes an individual block might not be to our liking, but in the whole of a quilt that changes. After I complete all the blocks, I lay them down on the floor and "audition" the blocks I'm not crazy about. Try them in different positions...sometimes they will help to balance out the color and then they blend better. If you can, leave the blocks spread out on the floor for a while, leave the room and come back later. I always tell DH that I am sneaking up on the quilt display....it seems to give you a different perspective. Good luck, maybe you could post pics?
