It seems like I always end up with one or two that are twisted in the middle. I press them flat. I know it shows up on the front (a little). Others will probably take it out and resew, but I have a hard enough time getting anything done, so, as long as you notice it from a galloping horse it is good for me! I used to try clipping them, but that does not make it look any better, and probably weakens the seam...
