Well, first I had to Google what they were. From the youtube video, it seems they are plastic reusable hexagons for English piecing. Hopefully the manufacturer will get back to you with a source. I wonder if the GourmetQuilter (quilter/teacher) from the UK might have them in her shop? If all else fails, I would buy some plastic quilt template material and make my own. Of course since you are fiat on your back that may not work for you, sorry.
