I just found this great tutorial on how to make an ironing board cover. She has an accent and sometimes it's hard to understand her. You really have to pay close attention. I think she said for the elastic 28" and it looks like she is doing the 28" twice. That will make 56" total. I'm going to make one, but I am going to try to slow down the speed when I get to that part so I can understand the inches part for the elastic.
