Haha, Anael....you would have figured it out. And, thank you! You don't need the thin fabric underneath hexi's. You can just zigzag them together as an option, too. I added that fabric because of the trapunto. I didn't want any of that loft stuff coming up through the quilt top. I used monofilament thread to join hexi's. You know me, I don't like to see stitches on my applique.
