Quilting away

I have been quilting the first third of my Cornucopia of Thanks quilt all week.  It's really a sampler with 12" blocks and somewhat unusual 6" sashing which sets the quilt apart.  Here's one of the blocks with the sashing.  I have done the blocks but now I'm trying to figure out how to quilt the sashing.  I have been using a very light gray on the blocks, with accents of multicolored thread.  I think I'll use black on the black sashing parts.  It's a very busy quilt, but I am loving the way it's turning out.
