Piano Keys Quilt Border

I have made a start.  Here is the first section of the border I am preparing for the Log Cabin Quilt (two pattern repeats so far).

Piano Keys Quilt Border for the Log Cabin Quilt

I just wanted to get a bit done as a sample.  The keys are cut at one and half by six and a half inches so finish up the same width as the strips in the log cabin blocks.  I rather like how this is turning out so far.

I am not sure how much of this I am going to need yet.  I need to park the piano keys, piece the centre section and add the narrow sashing.  I wonder if The-Much-Beloved will allow me any sewing time over the weekend.
