Its your quilt, you are the only one it has to please. I have found that when I ask others for their opinions on color, they steer me away from what the fabrics and my feelings are telling me to do for that quilt and go with their own. In the long run, its what is pleasing to you, not us.
I think stripes have their place in certain blocks. Not all blocks are suitable for stripes or directional fabric and may actually detract from the block itself. I find that stripes take a lot planning to get just right.. again, that's my opinion and there are lots on this list what will agree and disagree with me.. again, its your choice.
