This pattern is well written and the pictures are really helpful. The one thing I struggled with is that the seam allowance is not 1/4 inch - it's a very scant 1/4 inch. If you don't know that (and the pattern doesn't tell you), then you will find yourself ripping seams most times because they just don't match.
