This is another of the bases, fundamental to folding many models, including flowers, all kinds of containers and boxes, decorations and ornaments, coasters, picture frames, stars, etc.
In essence, the blintz base is created by folding the 4 points of a square piece of paper so they all come together at the center of the square, thus creating a smaller square.
It is possible to repeat the blintz fold more than once, which will then result in what could be called a double or triple blintz fold.
The instructions below are just one method of folding the blintz base, and by far the most accurate folding method.
For other methods of folding this and other origami bases, see this page:
Introduction to Folds and Bases Used in Origami
To fold the blintz base:
1. Place a square down on a flat surface with its edges left and right, top and bottom.
2. Fold in half from left to right and crease firmly. Unfold.
3. Fold the square in half from bottom to top and crease firmly. Leave folded.
You will now have a 2x1 rectangle in front of you with a long folded edge closest to you, 2 long raw edges furthest away from you and 2 short raw edges vertically on the left and right ends of the rectangle.
4. Take the top left hand corner and valley fold it down to touch the long folded edge so that the short raw edge that was vertical is now lying horizontally along the long folded edge.
5. Repeat step 4 with the right hand top corner.
6. Turn the paper over from left to right.
7. Repeat steps 4 and 5.
You should now have a right-angled triangle with the hypotenuse closest to you along a folded edge. It consists of 4 layers of paper:
the uppermost and lowest layers consist of 2 smaller right-angle triangles with their hypotenuse on the outer sloping edges. The 2 inner layers are large, plain right-angle triangles.
8. Unfold the long hypotenuse that is closest to you by bringing the top corner down.
You should now have a smooth surfaced square, arranged as a diamond, in front of you.
9. Turn the paper over and you have a blintzed square.
