Papercraft World | Paper Models | Free Papercraft | Printable Crafts | Paper Toys | Arts and Crafts Platonic Solid The Platonic solids, also called the regular solids or regular polyhedra, are convex polyhedra with equivalent faces composed of congruent convex regular polygons. There are exactly five such solids (Steinhaus 1999, pp. 252-256): the cube, dodecahedron, icosahedron, octahedron, and tetrahedron, as was proved by Euclid in the last proposition of the Elements. The Platonic solids are sometimes also called "cosmic figures" (Cromwell 1997), although this term is sometimes used to refer collectively to both the Platonic solids and Kepler-Poinsot solids (Coxeter 1973). The Platonic solids were known to the ancient Greeks, and were described by Plato in his Timaeus ca. 350 BC. Schläfli (1852) proved that there are exactly six regular bodies with Platonic properties (i.e., regular polytopes) in four dimensions, three in five dimensions, and three in all higher dimensions. If 1. all lie on a sphere. 2. 3. 4. 5. Let (sometimes denoted ) be the number of polyhedron vertices, (or ) the number of faces.
Gilad's Origami Page - Wetfolding How-to guide - Minefield Fold the model as you usually do, but with one exception. In regular folding, you may be used to putting creases in using your fingernails: In wet-folding, don't put such strong creases. If you feel the paper starting to get dry and stiffen while folding, use the cloth or spray-bottle to add some moisture, but try to not over-do it.
Origami is amazing - the traditional Japanese art or technique of folding paper into a variety of decorative or representational forms, as of animals or flowers. Origami is An Amazing Art now "origamoney"... koi carp butterfly camera tank dragon crab shark spider scorpion toilet and of course a penguin.. Please visit stories, etc. for more pictures, stories, etc. Math Craft Monday: Community Submissions (Plus How to Make a Modular Origami Intersecting Triangles Sculpture) Math Craft Monday: Community Submissions (Plus How to Make a Modular Origami Intersecting Triangles Sculpture) It's once again Monday, which means it's time to highlight some of the most recent community submissions posted to the Math Craft corkboard. I also thought we'd take a look at building a model that has appeared in numerous posts. It's the simplest of the intersecting plane modular origami sculptures: The WXYZ Intersecting Planes model. My wife, Elizabeth Poole, made some kirigami snowflakes based off of last week's instructions. I made a few more, as well. My wife also gave me an idea—making snowflakes based off of tessellations. Justin Meyers of Scrabble World posted up a link to a really cool how-to on making beautiful origami Christmas trees. Here's a "quick" version I made. Rachel Mansur posted up a plethora of links to some amazing origami artworks. Or maybe it was this picture of a giant Sonobe icosahedron: Or this picture of the Linux Penguin from Sonobe units: 1. 2.
Wet-folding Wet-folding bull Wet-folding is an origami technique developed by Akira Yoshizawa that employs water to dampen the paper so that it can be manipulated more easily. This process adds an element of sculpture to origami, which is otherwise purely geometric. Wet-folding is used very often by professional folders for non-geometric origami, such as animals. Wet-folders usually employ thicker paper than would usually be used for normal origami, to ensure that the paper does not tear. One of the most prominent users of the wet-folding technique was Éric Joisel, who specialized in animals, people, and mythological creatures such as fairies. The process of wet-folding allows a folder to preserve a curved shape more easily. Notes and references See also Papier-mâché External links
Flashback: Woven Map Basket Maps can be amazing design elements, with all their intricately drawn lines and minute details. But what do you do with a regular paper map that is starting to fall apart from use? In CRAFT Volume 05, crafter Jane Patrick suggested we weave maps into baskets, a fun and interesting way to reuse castoffs and weave a little memory into a functional item. Check out her full tutorial here and pick up a back issue of CRAFT Volume 05, the Paper issue, in the Maker Shed.Woven Memory Basket Weave your vacation road maps into an attractive souvenir. Materials 2-3 large road maps Contrasting string or thread Clothespins Cutting mat Rotary cutter Awl or tapestry needle Scissors Small tweezers White glue (optional) to further stiffen the basket Directions Step 1: Prepare the strips. Fold each strip in half lengthwise. Step 2: Weave over, under, over, under (plain weave) for a square base, 10 weavers in both directions. Step 3: Using string or thread, mark the base by twining around the edges.

[ Back to Origami Home ] Origami - Wikipedia, the free encyclopedia - Minefield The folding of an Origami crane Origami (折り紙?, from ori meaning "folding", and kami meaning "paper" (kami changes to gami due to rendaku) is the traditional Japanese art of paper folding, which started in the 17th century AD at the latest and was popularized outside of Japan in the mid-1900s. It has since then evolved into a modern art form. The goal of this art is to transform a flat sheet of paper into a finished sculpture through folding and sculpting techniques, and as such the use of cuts or glue are not considered to be origami. The principles of origami are also being used in stents, packaging and other engineering structures. History There is much speculation about the origin of Origami. In China, traditional funerals include burning folded paper, most often representations of gold nuggets (yuanbao). The earliest evidence of paperfolding in Europe is a picture of a small paper boat in Tractatus de sphaera mundi from 1490. Techniques and materials Origami Basic Folds Techniques
