Hello! This is Melissa from Poppy Bows!
This headband is 2 pieces. I make the top of the bow a loop, glue it in the center (like the letter B if that makes sense), fold it in half with a dot of glue in the center. Once that is dry, I take the bottom spike piece and incorporate it at this time and finish folding/glueing. That way it's as less bulky as possible
