Pick two colours of card that go well together. Fold the main colour of card in half.
Cut a long rectangle out of the second piece of card.
Lightly sketch out the design with a pencil.
Prick holes all along the design.
Take a needle and thread and stitch through the holes.
When you have stitched the whole pattern stick tape over the tales on the back for extra security.
Glue to the main part of the card. You're all done.
