Alright, while searching for the OBW fabric, I came across some additional blocks that I've already made a top from. The top is ready to be quilted, but needs backing. So I am going to make a scrappy pieced back from the leftover border fabric and leftover sashing fabric and the unused blocks!
Still searching for the OBW blocks and have now realized that I do not know where the book is either - found another completed top and some yardage that may work for the backing!
Well, I am giving up on the remaining fabric + the book. Guess I'll work on these additional UFOs since I've got all of the pieces/parts for them. Check out what others have on their Design Walls at Patchwork Times!
