It looks like the free pattern for YBR is 24 pgs. to print! I would strip piece a lot of the blocks, for instance sew two A strips together the WOF, then sub cut them. Sew two C strips together the WOF, then sub cut them. Sew together As and Cs, then sew to B.
There is also a Turning 20 pattern and a Turning 20 with a Twist pattern. Very similar and the instructions are easy to understand. Don't know about a free one for these.
