Refold the orange piece and slide it back in place and press down to set the glue. I put a glass on top of it until the glue dried.
Finishing the Card
Glue the large grey inner panels to the inside of the card. Tape glue is fine for this. Unfold the base card and place the point of the triangle of the two center pieces in the center of the base card (after the glue is dry). Lastly, with liquid glue, stick both sides of the triangle to the base card. Liquid glue is a must for this step because it holds better and is more permanent.
