Thank you all!!
I found this pattern in a Jelly Roll quilt pattern book from the Library. It looks quite complex but is very simple and goes together easily. It's from strips of any size light/dark/light/dark, I used 4, 1&1/4" strips which equaled out to 4 1/8" squares. You then cut on diagonals and piece them alternating light and dark.
I'm really scared to go into surgery and it means a lot that you all are here for me. The surgery is on my left knee and lasts about 3 hours and around 5 hours in recovery room. A screw and a plate will be left in my knee. Thanks for the well wishes, it's greatly appreciated. :-D
