Another quick fun fold is a gatefold card. Start with your standard card base, and instead of folding in half, score from both ends one quarter of the way toward the middle.
Starting with a piece of card stock that is 8-1/2" X 5-1/2", score along the 8-1/2" side 2-1/8" from each end. This card was created during my Facebook live on my page Monday, May 3, 2021. That video is also available here on YouTube.

OR for a landscape gatefold card, start with a piece of card stock that is 11" X 4-1/4", score along the 11" side 2-3/4" from each end. For the Designer Series Paper layer on the front of the card, use a 5-1/4" X 4" piece cut in half at 2-5/8".
