Clover Heart 4 is the fourth and final model in a series of Clover Hearts published in consecutive issues of The Fold. This one has the proportionately smallest clover.
A crease pattern and notes for folding a delightful heart with a color-change clover. Designed by Meenakshi Mukerji, it's a confluence of the works of Shuzo Fujimoto and Francis Ow. The clover can be extended into Fujimoto's Hydrangea as well as most designs that start with a four-sink base or crossed box pleat.
A fun crease pattern that can repeat infinitely to the center folds an octagon into a geometric flower design, where the front and back of the paper look the same.

This article explores several variations in a square twist crease pattern that may be achieved simply by varying the mountain/valley assignment of the same underlying crease pattern.
The first in a series on origami diagramming, this video focus on using Inkscape, a free vector drawing program, to draw origami crease patterns precisely.
Curved-crease origami can be designed by considering the properties of ruling lines, lines on the crease pattern that remain straight in the 3D folded form. This technique was developed by David Huffman, who identified conic section curves has being particularly suitable for curved-crease designs. Two examples using ellipses are given as crease patterns.

Several variations on a hexagon-based, iso-area, geometric collapse method are shown. Some of these were taught at the 2013 OrigamiUSA Annual Convention in New York City.
This article aimed at novice folders examines the design and folding process for geometric bowl and vase models characterized by a series of curved pleats.
The Zipper Tessellation is a good starting point for many variations, such as the Zipper Ring and Vase, presented here with crease patterns and some diagrams.

Tubis and Sprung show that the same starting shapes used previously to create generalized masu boxes [Tubis and Pooley 2012] can be used to produce \(n\)-pointed 3D stars.

Tubis and Pooley explore \(n\)-sided generalizations of the masu and one of its many decorative-lids. Detailed video instructions are provided at the Origami Player site.
This article describes techniques for finding reference points for models with square root of two ratios which are commonly found in 22.5 degree designs.

The addition of curvature introduces some situations which conventional crease patterns are not good at dealing with. I present some ideas for incorporating surface curvature into crease patterns, and discuss why I chose these schematics.
With many tessellations, the obvious way to design the crease pattern doesn't necessarily result in a foldable pattern. By adding extra creases to the pattern, you can sometimes find an alternate way to the finished form, as you'll see in this geometric pattern.

Crease pattern for Toshikazu Kawasaki's Dragon inspired by a statue in Barcelona. OrigamiUSA members have contributed diagrams and a video tutorial for this model as well.
The first in a series, analyzing crease patterns. In this article, we take a big picture look at a Werewolf designed by <a href="http://www.flickr.com/photos/53465278@N02/" target="blank">Jacob Rossman</a>.

Making a crease pattern takes less time than drawing a full diagram, but because of the technical difficulty, most folders don't like working with them. Here's some ideas about how to make things easier without spending dozens of hours on a full diagram.
