They are a really neat project especially if you are on the go. The plastic hexagons are pricey. I was taught to just do a running stitch and gather it tightly. This method of taking a few tucks is interesting. When stitching the hexes together, having the thickness of the plastic makes it much easier to conceal the stitching being able to get more towards the back side of the edge. But with PP hexes. so much faster to use a glue stick to fold the back over the edges of the hexes..
