Florence and Mary - I can't remember the size of the block and forgot to mark it down before it went of to the long arm quilter. Sorry. But someone did answer that. But if you square it up leaving a hair mite than a quarter inch, like 1/8'' more, off the point of the star block, you will be fine. Then will have plenty to square up the final size of 16-1/2''.
Mary, yes, I did grab the cabana boy, too, along with the goodies I left out for you. might share him, might not ...... I stashed him in my cabin.
