Patreon for origami creators — 2026 guide

Yoshizawa-Randlett notation valley and mountain folds, kami tissue-foil washi paper by gsm, wet-folding methylcellulose sizing and moisture window, Sonobe and PHiZZ modular polyhedra, crease pattern design from tree theory, and the Apple Tax.

Origami Patreons retain when they deliver the technical layer that diagrammed tutorial videos structurally omit: the Yoshizawa-Randlett notation system and why each fold symbol encodes both direction and plane of reference, paper selection by fiber content and gsm for each technique category, the wet-folding moisture window and methylcellulose sizing chemistry, modular unit geometry for polyhedra construction, and crease pattern reading from a CP bitmap to a finished model. Plus the Apple Tax for origami audiences starting November 1, 2026.

Yoshizawa-Randlett notation: the diagramming standard

Akira Yoshizawa developed a universal folding notation in the 1950s; Samuel Randlett and Robert Harbin standardized it in book form in the 1960s. The system encodes every fold with two components: line style (indicating the fold axis on the paper surface) and arrow style (indicating the direction of movement). Valley fold: the paper is folded toward you, producing a concave valley crease when opened; diagrammed as a dashed line (- - - -) with a folding arrow curving toward the viewer. Mountain fold: the paper is folded away from you, behind the model; diagrammed as a chain-dot-dash line (—•—•—) with an arrow showing the paper moving behind the model; the resulting crease is a convex ridge. Reverse fold: the apex of a flap is reversed along a crease, changing the mountain/valley assignment at the fold axis; the inside reverse fold pushes the tip inside the layers (used for beaks and feet); the outside reverse fold wraps the tip around the outside (produces a wider angular change). Squash fold: a flap is opened and pressed flat symmetrically, transforming a triangular flap into a square or diamond. Petal fold: a compound move that lifts a point while squashing the two flanking creases flat; applied to the preliminary base it produces the four-flap bird base. Sink fold: a tip is pushed into the interior of the model, inverting a point to a pocket; requires the paper to be open enough to access the interior, which is why sink folds appear late in complex sequences after structural layers are locked. Crimp: two parallel mountain and valley creases displaced by a short distance create a Z-section; used to offset a flap at a given angle without reverse-folding. The notation system's mathematical encoding is why origami design software (Robert Lang's TreeMaker, the Origami Simulator web app) can simulate models from crease pattern coordinates alone.

Paper selection by gsm, fiber, and technique category

Paper selection is the primary variable separating achievable models from impossible ones for a given folding sequence. Three properties matter: gsm (grams per square meter), fiber content and length, and sizing (how the paper responds to water and moisture). Kami: 60–70 gsm; pure cellulose; solid-colored or patterned; holds valley and mountain creases with good definition; the standard paper for learning and intermediate models; too thick for complex models with more than approximately 30 steps because accumulated layer bulk at fold intersections prevents the model from closing into its final form; pre-cut squares 3 cm to 35 cm are widely available. Tissue foil: 15–20 gsm; a laminate of thin tissue paper (3–7 gsm kraft or gampi) bonded to aluminum foil with diluted methyl cellulose or PVA emulsion; the foil layer locks creases permanently by plastically deforming the metal layer while the tissue provides tear resistance; required for complex and super-complex representational models (Robert Lang insects, Eric Joisel masks and figures) where 100+ step sequences accumulate layer counts of 12–20 at the most complex intersections; self-made tissue foil allows selection of foil weight (0.01–0.02 mm), tissue type, and sizing concentration. Washi and kozo: handmade Japanese paper from kozo (paper mulberry, Broussonetia papyrifera) bast fiber; the long interleaved fibers give exceptional tensile strength at low gsm (10–30 gsm) and resist tearing along fold lines; unsized washi is ideal for wet-folding because the long fiber network accepts moisture and holds three-dimensional curves after drying; random fiber orientation in hand-laid washi (vs machine direction alignment in machine-made paper) is a wet-folding advantage because compound curves are multi-directional; Ogawa washi and Awagami washi are commercial sources with consistent gsm documentation.

Wet-folding: methylcellulose sizing and moisture control

Wet-folding is a technique developed by Yoshizawa in which dampened paper is shaped into organic three-dimensional curves and compound surfaces that flat creased paper cannot hold. The paper must contain a sizing agent that stiffens as it dries: methylcellulose (MC, also sold as tylose or CMC) is the standard wet-folding sizing because it is water-soluble when cold, gel-forming above approximately 50°C, reversible on re-wetting, and archival (adds no acidity). MC powder is hydrated in cold water to a 0.5–2% concentration solution; higher concentrations (1.5–2%) produce stiffer, more brittle finished forms used for display models that will not be refolded; lower concentrations (0.5–1%) allow post-drying adjustment. The critical moisture window is 8–15% by weight of the paper: below 8% the paper is too dry to bend into smooth curves without cracking along the fiber direction; above 15% the paper loses structural integrity, tears at stressed intersections, and holds its position poorly during drying because the wet fibers cannot sustain tension. Application: spray the paper lightly with a fine mist of water or diluted MC solution from 30 cm; allow to equalize for 1–2 minutes under a slightly damp cloth; test by bending a corner — correctly moistened paper should hold a gentle curve without springing back but not feel wet to the touch or transfer moisture to dry fingertips. For complex models, apply MC selectively by brush to specific regions requiring curve retention (animal flanks, wing surfaces) while leaving crease-fold regions drier so valley and mountain folds remain sharp and well-defined. Drying requires holding curves in position: foam cradles shaped to match the model's contours, wire armatures threaded through folded channels, or temporary stuffing with loosely crumpled tissue paper. Room temperature drying: 4–12 hours depending on paper weight and ambient relative humidity; 50–60 RH% room and a low-power desk lamp at 30 cm will reduce drying time without cracking.

Modular origami: Sonobe and PHiZZ units for polyhedra construction

Modular origami assembles three-dimensional solids from multiple identical units connected by pocket-and-tab joints, with no adhesive. The two most widely taught unit types are the Sonobe unit and Tom Hull's PHiZZ unit. Sonobe unit: each unit produces a triangular face with a 45°/45°/90° right-isoceles geometry; one edge carries a pocket flap and the adjacent edge carries a pointed tab; the tab of one unit inserts into the pocket of the adjacent unit with a 90° dihedral angle between faces; assembly counts and resulting solids: 3 units = triangular spike; 6 units = cube (with each face showing a pinwheel arrangement of 4 triangular faces); 12 units = cuboctahedron; 30 units = stellated icosahedron (a sphere-like spiky ball); each unit interlocks with exactly two other units so that a completed assembly holds its geometry by friction through the paper layers with no adhesive required. The Sonobe assembly is the starting point for teaching graph theory concepts (assembly graph, vertex degree) and topology (the relationship between vertex count, face count, and edge count in a closed polyhedron satisfying Euler's formula: V − E + F = 2). PHiZZ unit (Pentagon-Hexagon Zig-Zag, Tom Hull, 1990s): a unit designed specifically for polyhedra with both pentagonal and hexagonal faces; 30 units assemble into a dodecahedron (12 pentagonal faces, 0 hexagonal faces); 90 units assemble into a truncated icosahedron (12 pentagons + 20 hexagons, the topology of a soccer ball and a C60 buckminsterfullerene molecule); at every vertex of the PHiZZ assembly exactly 3 units meet, with angles of 120° at hexagonal vertices and slightly more acute angles at pentagonal vertices; coloring units strategically so that no two adjacent faces share a color requires solving the face 3-coloring problem on the face-adjacency graph of the polyhedron, which is solvable in 3 colors for the dodecahedron and truncated icosahedron and is a practical mathematical exploration for advanced origami tier content.

Crease pattern reading and design from tree theory

A crease pattern (CP) is a flat diagram of every crease in a completed model, mapped back to the unfolded square and coded by mountain or valley type. Reading a CP requires understanding that it encodes the final geometry, not the folding sequence: the folder must derive the sequence from the crease geometry. Flat-foldability conditions: Maekawa's theorem states that at every interior crease vertex, the difference between the number of mountain creases and valley creases must equal exactly 2 (so legal interior vertices have mountain/valley combinations of 1M/3V or 3M/1V for a 4-crease vertex, for example); Kawasaki's theorem states that at every interior vertex, the sum of alternating sector angles must equal exactly 180°. A CP in which every interior vertex satisfies both conditions can be folded flat without tearing. Tree theory and circle-river packing: Robert Lang's TreeMaker software formalizes the mathematical basis of uniaxial base design. Every uniaxial base (a flat base whose flaps map to the branches of a tree graph) can be derived from a circle packing on the square where each circle represents one flap and has a radius equal to the flap's length measured in units of the paper's side length; rivers (non-circular regions between packed circles) correspond to internal branches of the tree. The CP crease set is then the set of creases that simultaneously fold the circle-packed square flat onto the tree structure, satisfying both Maekawa's and Kawasaki's conditions at every vertex. This is why complex insect CPs have concentric arc structures: the arcs are boundary creases between adjacent circle-packing regions. For tier content, annotated CP walkthroughs that trace from the target model's tree graph through the circle-packing solution to the final CP are the highest-retention content for technical origami audiences, since all published diagram books skip the design derivation entirely.
