. . . I came across a Diamond Fold card a few weeks and just had to have a play!!!
Here's how to make a Diamond Fold card:
Draw a vertical pencil line through the centre of a horizontal piece of paper/card cut to 12"(30.5cm) x 3.75" (9.5cm). Fold the bottom two edges upwards to meet the pencil line. Unfold. Repeat with the top edges (folding downwards). This gives you two folded crosses.
To the right and left of the pair of crosses, fold to create the side panels. Compress the sides inwards to form 'hills and valleys' and in doing so, the diamond card.
I do hope you like my card,
wishing you a wonderful day, Sam xxx
