This double Z Fold card is simply a piece of 6" x 12" Designer Paper scored at 2", 4", 8", 10". Measure from the bottom on each side, 3" and cut up to the 4" scoreline removing the triangle. Repeat this on the opposite side. Glue these triangles to the bottom on the inside. See photos on my blog at https://wp.me/p3deDV-6QQ
