Ok - I have this book and I attempted this pattern this last week - Ugh... I am having such a hard time with the diamonds- I made the large diamond blocks and added the x and y borders then when I sew the 4 pieces together - it gets poufy in the middle where the diamonds line up - is there a secret? I have one of the star blocks done and started another one and its not as poufy - but I find this to be very frustrating - help!!!
