Paper Weight and Texture Guide

Paper Type Weight (gsm) Texture Best Uses Pros Cons
Kami 60-80 Smooth, slightly textured Learning, traditional models Affordable, holds creases Tears easily
Tant 78 Textured, fibrous Complex models, wet-folding Strong, beautiful texture More expensive
Foil-backed 50-70 Metallic backing Decorative models, gifts Shiny finish, holds shape Harder to fold cleanly
Washi 25-40 Handmade, fibrous Artistic pieces, large models Traditional, unique patterns Delicate, expensive
Tissue Foil 25-30 Thin, metallic Ultra-complex models Extremely thin, strong Very expensive, hard to work with
Copy Paper 80 Smooth Practice, quick models Cheap, readily available Poor crease retention

Colour Symbolism in Traditional Origami

Colour Traditional Meaning Best Models Cultural Significance
Red Good fortune, joy Cranes, flowers Celebrations, weddings
White Purity, peace Cranes, lotus Funerals, meditation
Gold Wealth, prosperity Dragons, boxes New Year, business gifts
Blue Tranquility, water Fish, boats Calming, water themes
Green Nature, growth Frogs, leaves Spring, new beginnings
Purple Nobility, wisdom Complex models Respect, honor

Troubleshooting Common Problems

Problem Cause Solution Prevention
Paper tears Too much force, wrong paper Use lighter touch, switch paper Start with quality paper
Uneven folds Rushing, poor alignment Take time, use ruler Work slowly, check alignment
Won’t hold shape Weak creases, wrong paper Press firmly, try heavier paper Use bone folder
Model collapses Insufficient tension Reinforce key folds Follow tension guidelines
Can’t follow diagram Complex symbols Study symbol guide first Practice basic symbols
Proportions wrong Measurement errors Double-check each step Use precise measurements

Advanced Techniques and When to Use Them

Technique Description Difficulty Best Applications Time Investment
Wet Folding Dampening paper for curves Advanced Organic shapes, animals High - requires practice
Modular Origami Multiple pieces assembled Intermediate+ Geometric shapes, kusudama Medium - repetitive
Tessellations Repeating geometric patterns Expert Wall art, mathematical models Very high - complex planning
Crease Patterns Pre-planned fold lines Expert Original designs, efficiency High - requires math skills
Kirigami Combining cutting with folding Intermediate Pop-ups, decorative pieces Medium - needs cutting skills
Action Models Moving parts and mechanisms Advanced Interactive pieces, toys High - engineering concepts
