Tutorial For Double Diamond Fold Card.
Firstly you need to take a 12" x 5" piece of cardstock, and fold in half (2.5") horizontally.
Then you need to score 2.5" vertically from both, the left and the right hand side in.
I have marked with pencil - 4 3/16" from both left and right, top and bottom. Also on the horizontal line I have marked, (although not very clear in the photograph) at - 3 1/8".
When you have marked all your measurements, join the dots and flip the card over. This is what you will have achieved, in such a small amount of time.
All that is needed now is to crease your fold lines. In this picture I have creased the lines, and left the card so you can see the valley and mountain folds.
Now all you need to do is, push both sides in while ensuring the horizontal line folds in half also. Then you are left with this card fold, that looks so complicated but yet is so simple.
