Pam, my suggestion would be to try meanmom's ideas and if they don't work stop worrying about it. My guess is that it will be hard to go over it and have your stitches end up exactly on top of it. Also, sometimes we are our own worse critics and other people probably don't notice it nearly as much as you do. I think your sister is going to notice that she has a permanent reminder of your love and support and not that there is something not perfect.
