This is such an easy quick card to make. I found a video on Youtube video while looking for some new and exciting folds. I am afraid I didn't take a huge amount of notice of who the lady was that made the video. But I do remember her calling this a double tower card. The reverse has a panel on to write your message on.
Here is an end on view of the card so you can see that it stands.
Yes it does fold flat so it fits in a 7 x 5 envelope nicely.
P.S. Forgive the white paint on my hands I've been a little busy the last few weeks painting the house. some of the paints require a lot scrubbing to remove them from the skin and nails.
