Here's an easy way to fold any rectangle of paper into a triangle with three sides the same length.
- Fold the paper in half long-ways, then open it out flat.Image
- Fold a bottom corner up to touch the fold line, making a sharp point on the other corner.Image
- Now fold the two RED edges together.Image
- Fold under the corner and then tuck it in out of the way. Turn over to the smooth side.Image
- Now why not make some more from coloured paper and create some designs.
