I did that one. It's been awhile but I think I did stitch in the ditch since I didn't want to take away from the directions of the piecing. By the way, did you end up with a curve in the piece when completed? I followed the directions as they were online at the time--said to always begin at the same end when stitching and I ended up with a nice curve toward the end. I didn't use the entire "foundation" but still have that extra with the curve in it to figure out how to use that.
Love your colors--nice job!
