Traveling Stars layout

I've decided on a staggered layout with no sashing for my Traveling Stars quilt.  This would look good on our queen size bed, so I've been doing a little math.  

These blocks are 11.5" unfinished.  So if I make it 8 blocks by 10 blocks the finished quilt will be about 88" x 110".  And that would mean that I need 80 stars and so far I have 47.

I'll add a white strip to the top of every other row, and the same strip to the bottom of the other row.  That would be vertical rows, so that the sides will all be even.  

I'm linking up to Judy's Design Wall Monday so check out what is going on in the quilting world.
