Hi,
I am definitly new at this also, so hopefully someone else will double check this for you. You should end up with a 9 patch block (3 blocks wide by 3 blocks long) and the total for the single pieced block will come out at 11" square. this would be using accurate 1/4" seam allowances.
And just to clarify... this would be the block before sewn into the quilt with any sashing. This is where you would square them up a 11".
