TAST Week 20 Butterfly Chain stitch

Week 20 saw us doing Butterfly Chain stitch and again I had not heard of this stitch before-but again I found it a most enjoyable stitch to do.
I have used 28 count Gobelin and Perle 5 thread.
I got a bit wonky at the end of the blue row but I left it in and I will call it a creative treatment.I hate playing catch up like I have been the last few weeks but I will try to hard to keep up in future,
