Regarding the measurements, my standard is WOF 12" on inside and 18" for the back/sides. I've made several sizes - one of which was for a small table and it was very narrow. The lace is really a cute idea. I've used the rick-rack on the short ends and also lots of buttons & findings. Since I'm from Nebraska, I've made quite a few of the Nebraska Cornhusker (football team) runners and they're always a hit.
