All designers fold. Templates 6. The World Is Flat 3. Convert to PDF. Parabolas 5. Basic Parabola 5. If you want to impress someone with a folded structure that fascinates both the eye and the mind, a parabola has to be a contender. It is imperative to master this before you attempt any of the others. All the folds must be made with care so that every concentric square is made with great accuracy. If you become a little lost placing the folds and your sheet is messy, it is better to start afresh rather than continue.

Please turn to the page and learn or relearn how to do this. You cannot proceed until you know how to divide a sheet into Make described in the previous sure that each concentric step.

Notice three square is made only of important things: how each mountain or valley folds fold is contained entirely not a mixture of the two within either the top or and that the squares the bottom triangle; how alternate valley-mountain- no fold touches the edge valley-mountain between of the square; and how the edge of the sheet and there is no centre fold the the centre point.

To do the time. Note how each this, hold the paper in the corner collapses to make air, thumbs on the front a familiar V-pleat.

Note how a pair of not folded strongly. This opposite corners will is best done by making gradually rise up, while the paper more and more the other pair will dip stick-like, rather than by down. As you fold more and more concentric squares, the parabola will become more and more 3-D.

The more the strongly to strengthen parabola is opened, the the folds. For transportation or storage, collapse it back to the stick form. Variations 5. Variations Once the basic square parabola has been mastered, it is possible to make many variations, using the same principle of dividing the sheet into 16 from the edge to the middle.

This means that the edge of one parabola can be fully connected to the edge of another, allowing complex structures to be built up from many joined parabolas. Not for the faint-hearted, this is a one-sheet crease pattern for four basic parabolas in a 2 x 2 grid, so that four parabolas meet at the centre point.

It is possible to remove one of the parabolas from the 2 x 2 grid and close the gap by glueing the edges together, thus allowing only three parabolas to meet at the centre point. The possibilities are immense and surprising. The example right shows four separately folded parabolas joined with pegs.

If you are folding it by hand, you may need to draw extra construction lines in light pencil to help you keep all the folds parallel and equidistant. See photo on previous page. Masu Box In origami, boxes and bowls abound. There are hundreds of different designs that could be described variously as boxes lidded or unlidded , trays, bowls, bags, dishes, pots, vases or containers. Some are simple, square and functional; others are very decorative.

They can be made from squares or rectangles, or from other polygons. Origami hats may be considered box forms, and vice versa. Making boxes is the art of making corners. This chapter presents just a very few of the ways to make square, vertical-sided boxes. A little research will reveal many more. Consequently, it is easier to create your own bowl designs than ones for boxes.

Boxes 6. Masu Box The Masu box see photo opposite is a traditional Japanese design. Masu Box 6. Fold the divide the sheet into four corners to the centre.

Similarly, fold the left and edges to the centre point. Unfold the top and bottom triangles only. Several things This is halfway.

Corner H lifts the vertical, F and G are almost touching, up to the vertical. E touches D. H is vertical, Repeat Steps 11—13 with the other end The Masu box is complete. Lock the end of the box tightly by wrapping corner H over the top of the box. Masu Variations 6. Masu Variations The previous section gave the basic method for making the Masu box. Here are two examples. This will make a shallower box. The method for completing the box is exactly the same as for the basic Masu except that corners F and G will not fold in far enough to touch.

If the folds are made along the D divisions, the box will be a lidless cube. The method for completing the box is exactly the same as for the basic Masu except that corners F and G will overlap, not touch. Roll Box 6. Roll Box The elegant rolling technique used here to create the box ends is a variation of the Box Spirals in 3.

Many other box ends can be made by combining the examples shown in 3. The box can be any length and only one end needs to be rolled closed — the other can be closed using another box-making technique, or simply left open. Open the folds. Refold the left closed. Fold the top pair of Individually fold a diagonal and right sections of the left and right diagonals, as in each of the squares, four horizontal valley folds shown, rotating rectangle parallel to the folded edge as mountains.

A to the vertical. The sheet of the triangle above it. Note how the two ends of the box slowly create a series of triangles, each one on top of the one made previously.

Corner Gather 6. Corner Gather The technique shown here for gathering and locking a corner can be adapted to work with other polygons, not just a square. The sides can be made taller or shorter relative to the base, depending on where the folds in Steps 1 and 2 are placed. By changing the angles of the gather in Step 14, the sides can be made to splay out like a bowl, rather than rise vertically. Unfold the Unfold the diagonal. Fold corner to corner As in Step 4, fold up the small triangles.

Unfold the diagonal. This is the pattern of valley folds made so far. Corner Gather A 6. This is the crucial step. Create separately This is now the shape of the paper. The next step shows a close-up of already a valley, but strengthen it. The paper will now become 3-D and make a convex corner at A. The corner is now complete. This is the completed box. Repeat Steps 13 and 14 with the remaining corners.

Bowl Forms 6. Bowl Forms New bowl forms are easier to design than new boxes because the design parameters are wider.

When these variations are combined in different ways, even the simplest ideas can create many diverse forms. Be the first to ask a question about Folding Techniques for Designers. Lists with This Book. This book is not yet featured on Listopia. Community Reviews. Showing Average rating 4.
