I am getting ready to make a twin size quilt for a friend's little girl. She wants an Easy Cathedral Window Quilt like Jenny Doan of Missouri Star Quilt Company illustrated in her tutorial:

The windows will all be pale pink with sides pale green and of course white around the pink centers. My problem is the pattern I bought from MSQC is for a table runner. I have no idea how to figure out the yardage needed for a twin bed. Can anyone help me?
