Bridge Of Sighs
Rate this posting:
Any pop-up form that straddles a gutter crease to generate extra creases that can become new gutter creases that can become new gutter creases to generate more pop-ups and so on. This technique, used with the Cut Away technique, is the most useful of al one-piece techniques, permitting the combination of any or al the preceding techniques, in whaterver form. An understanding of its basic principles, and a little patience in construction, will eventually lead to a mastery of one-piece pop-ups.
The Generations techniquehas many applications. Each of the variations highlights a major technical theme for the reader to explore.
1. Fold a sheet of stiff paper in half. Draw two horizontal lines from the gutter crease and join them. Cut along the horizontal lines. (For clarity, coloured lines have been used here, but you should draw in pencil.)
2. Make a crease between the ends of the slits, folding the paper forwards then backwards along the same line.
3. Open the sheet of paper. Create a conventional pop-up by pulling the step shape must from simultaneously. The pop-up will have one mountain crease, and the rest are valleys.
4. Close the pop-up again and repeat step1. You should cut through all four layers of paper, ending halfway across the remainder of the sheet.
5. Repeat step 2 and crease beteween the ends of the slits. Open the paper out once again.
6. Create two new smaller pop-up, using the same method as in step 3.
7. Repeat the procedure, this time to make four new pop-ups
8. And repeat again, this time to make eight new pop-ups.
This is the spectacular result; Given a large enough sheet of paper, the four generations made here could be extended to five, six or even more, with each new generation doubling the number of steps.
Bridge of Sighs:
Height 11 cm (4 1/4 in ). The sophisticated use of the Generations technique, frequently coupled here with the Cut Away technique, creates a convincing sculptural effect. Note how the gondolier in the right foreground gives a sense of scale to the bridge.
