Ohhh I knew I'd get GREAT advice! Thanks to everyone that has 'helped' me. I'm so wanting this to turn out nice I've probably over thought it! I will probably use matching thread and just go down the center. I never gave it a thought that the baby would like the tactile of the curled edges. There is about 180" of rick rack so following the curves seems daunting for this project :0) Did I mention I want it done! :0)
