For each model: one piece Kami bicolor square 15x15cm (6x6 inches)

One square, recommended size of 25cm (~9.75") or larger. Kami, kraft, washi deluxe, or other sturdy duo papers.

Recommended paper: One 9-inch (23 cm) square (or larger), kami or sandwich paper, single-sided (preferably brown). A pre-creased grid of 11x11 squares is recommended prior to class, but I will also teach you how to pre-crease the grid and fold the tessellation during the class. You will also need a square sheet half the size of the paper you're using for the box of brownies to fold the knife (if there is time to teach it).

Two 6 inch (15cm) sheets, for the single-molecule, and two 10 inch (25cm) sheets for a 2 by 2-molecule projects.

8 sheets of double color, 80 Grams or higher (Printer paper, Astrobrites, Tant).
All sheets should be same size: 10*10cm or 15*15 cm or 20*20 centimeters (4"x4" or 6"x6 or 8"x8")
Kami paper can function but the result isn't very stable
Craft paper is fine.
Good vibes
Joy
No glue, no scissors

An iPhone or an iPad with OrigamiDraw installed and separate from the device used for Zoom is recommended but not mandatory. Some familiarity with Crease Patterns (CP) is required (hence the “High intermediate” rating); this class will not teach what a CP is. Nevertheless, it might give some ideas on how to read a CP, and how to draw one for a new model.

Square origami paper at least 10 inches by 10 inches (25 x25 cm) any larger sized sized paper. Plain origami paper would be suitable.

You will need:

30 sheets of 7.5 cm (3 inches) origami paper, anything 2 cm (1 inch) up or under will be fine too. The reccomended paper type is kami with 2 different sides. Harmony paper will give the pretty gradient effect

At least two squares of paper 6 x 6 inch (15 x 15 cm). You can use kami paper or cut squares out of computer paper. A couple of paper strips about 4 inches x 3/8 inch (10cm x 1cm).

It can be made from 4 pieces of standard kami paper (white one side). You'll need 1 piece of white paper 15x15cm (6 x 6in) (to be cut into 2 triangles), 1 piece of 5cm x 5cm (2in x 2in) red paper, and a black piece 7.5cm x 1.25cm (3in x 0.5in).

Various paper.

A single sheet model, 15CM (6 inches) is a good size.
Students MUST prepare 1 sheet pre-creased grid:
• 16x16 grid square MOUNTAIN folds on the color side
• 32x32 diagonal VALLEY folds on the color side

Suggesting Harmony paper, but regular Kami or Kraft paper gives good results.
Tant and Astrobright work well, but paper with different color sides is recommended for the first time.
A bone folder and a bamboo skewer or other pointy tools are a good idea.

Best paper for following along will be foil-backed paper, 30 cm (12") preferred; but doable from 10" (25 cm) paper, either kami or foil. Once you're comfortable with the folding sequence, any heavy wet-folding paper works well.

10" (25 cm) square paper for each model. Prepare three sheets for three designs. Flatfish and Coelacanth have a color change.

For this model, you will need 10 square sheets of 3 inch (7.5 cm) paper. The paper should be on the thinner side. Kami is perfect.
The model on the left uses paper with pink on one side and yellow on the other.
The model on the right uses paper with the same color on both sides.

The paper doesn’t need to be duo paper. You’ll need a sheet for the bag and another sheet for the heart.
Kami is fine, or a slightly thicker paper works too. Make sure you have extra paper on case.

1. The base of the bag = 6" (15cm) paper
2. Large heart attachment = 6" (15cm) paper
3. Medium heart attachment = 6" (15cm) paper
4. Small heart attachment (if there is enough time) = 6" (15cm) paper

1 sheet of kami colored on one side, white on the other. Ideal size is 10-inch, but 6-inch will work.

One sheet of 9 X 11 inch or 22.5 X 30 CM, scrapbook paper works well.
CM/Inch Ruler, pencil or pen
Small amount of measuring required

30 pieces of 6 inch (15 cm) kami. They can be all be one color, or you can use combination of color (for example, 6 colors x 5 pieces per color = 30 pieces)

One square of origami paper - kami works fine. Size 6 inch (15 cm) is good for learning. 3 or 4 inch (7.5cm or 10cm) also works well.

The best paper is a square over 24 cm (9.5 inches) with a white front and a black back.

10" (25cm) kami or foil backed paper - duo colored

Any 6 inch (15 cm) kami.

One 25x25 cm^2 (10x10 in) square of kami paper will suffice to understand the folding sequence of the model.
Thicker paper such as elephant hide and watercolor paper will produce better results since this model is suitable for wet-folding.

- Scissors
- Tweezers are optional but recommended
- Optimal paper size is a 10” (25cm) square and must exceed 6” (15cm) in both length and width (the larger the paper, the easier the model)

15 cm or 6" kami or slightly thicker

Standard six inch square origami paper.

Made from one square of paper. Kami is ideal. 4-inch (10 cm) and 6-inch (15 cm) are ideal. A folding bone is helpful but not necessary.

Please come to class with one or more boxes of Kleenex tissues in any of the following three sizes:

Firstly, the smallest, a “100 flat” (that means it contains 100 tissues) - also known as Kleenex Professional brand tissue - measuring about 2” (51mm) high x 4.8” (122mm) wide x 9” (228mm) long. This is my favorite size, but it is often the most difficult to find unless purchased by the case.

Secondly, the medium height box, a “144 flat”, measuring about 3.5” (88mm) high x 4.6”(118mm) wide x 8.9” (225mm) long.

Thirdly, the large box, a “190 flat”, measuring the same width and length as the second above, but 4.6” (118mm) high.

You will want to have on hand some kind of practice paper from which to make a preliminary cover. This will be used as a template for making the finished model. I recommend a roll of brown or other wrapping paper not less than 20” wide.

Also, have on hand two tools: firstly, a means to cut the paper - this could be an “Envelopener”- type of cutter or a pair of scissors, secondly, a table knife or a credit card to tuck the paper into place. Thirdly, some nice quality paper for the finished Kleenex box cover.

For this cover, I like to use paper which, when folded, will yield flat, taut surfaces and crisp folds. My favorite papers to use are Cavallini brand posters (500mmx 700mm) which yield two box covers per sheet. The “Paper Source” is one such place to find this paper.

El modelo comienza como a partir de un rectángulo de proporciones 1: 2,5 , pero para la clase una medida aproximada es traer una hoja A4 y cortar un cuadrado, el rectángulo que sobra sería el que utilizaríamos.

Es decir, pedir para la clase solo 1 hoja A4, allí les diría como formar el rectángulo.

No supplies needed.

Sheets:
Total 2 pieces: one piece (1) for rose and one piece (1) for calyx).

Size:
Two pieces 20cm to 30cm (≈7.8 in to 11.8 in). Only experienced folders might fold it from from 15 cm (6 in) square. Smaller sizes are not recommended.
Final model is large in diameter and high roughly as 1/4 of length of initial square.

Suggested type of paper:
Light-medium weight (≈50 to 100 gsm), stiff, resistant to tear, with good memory (crimps, reverse folds), with smooth texture.
Any of these paper works well: Tant, Sirio (Fabriano/Fedrigoni), biotope, kraft paper, bread/sandwich paper (food kraft), sketch paper (e.r. „Schizza e strappa“ by Favini), lighter embossed efalin/estralin, lokta paper or similar.

In absence of previous listed or similar, not suggested (less nice result).but possible to use the common kami or sealing (coloured striped kraft).

Proportions:
The square of calyx is smaller with side equal half diagonal square for rose
As square of size of blintz base folded from of square for rose.

Tools:
• 4 clips,
• Crochet tool with thin head or scrapbooking tool or wooden skewer or tweezers.

8 to 10 Kami sheets, 4 to 6 inches (10 to 15 cm) in size.

25cm/10inch or larger squares suggested. Thin duo colored "kami" or origami paper works well. Thicker washi or Chiyogami not recommended for swimming action.

• 2 sheets of the same size paper, preferably Tant and preferably larger than 15cm (6 inches) square. Kami is fine, but thicker paper would work better. This will work with any paper you can grid and reverse the creases.
• Bone folder
• Crease Pattern or folded sample of a tessellation where repeating elements are not aligned with the grid

- 1 double-sided square piece of paper (It can be white with other color), of size 20x20cm (8x8 in). The finished model is about a quarter of the original, so it can be made with smaller or larger sizes. There is no strict type of paper but preferably a strong and light one.
- (Optional) Bone folder to the ones who feel comfortable with it.

• 4 pieces of 2-6 inch (5-15cm) square kami or other similar weight paper
• larger paper recommended for less skilled folders: preferable 4 pieces of 6 inch (15cm) and 4 pieces of smaller paper (7.5cm)

A6M Zero Fighter: 25x25cm (10x10 inch) paper. One coloured paper for best results.

a) 12 6" (15cm) square pieces of paper. They can all be the same color or different shades of one color (For example: 4 sheets each of 3 shades of blue or  3 sheets each of 4 shades of blue). 
b) A pair of scissors. (We will start by cutting each piece of paper into a pentagon.) 

For each box we will need 6 sheets (3 sheets for lid and 3 sheets for container)
Printing paper (75-80 gsm) works well, such as Astrobrites (24 lb/89 gsm).
• 11 in by 8.5 in (US Letter), or
• 210 x 297 mm (A4)

You can download and print these patterned sheets designed by me. It was a part of an article that I published with Math Horizons:

***The Zoom recording for this class begins at 1:51:00.

Hexagon box bottom and top: 12 squares + one extra sheet to make a template: 15 cm (6 inch) recommended, bigger is fine. Smaller is fine if you are an experienced folder. Duo paper is great for the top (6 squares) because the back will show. The back will not show for the bottom. Kami or light weight duo are good choices for paper since there are multiple layers of paper in the finished box. Heavier paper could be problematic.

Triangle box bottom and top: 6 squares: 15cm (6 inch) or larger is fine just for learning the box.

If you want to make triangle boxes that nest in the hexagon box as shown, you need 3 squares for each box bottom (so a total of 18 squares) that are 1/2 the side length you used for the hexagon box. For example, if you used 15 cm (6 inch) for the hexagon box, you need 18 squares of 7.5 cm paper (3 inch). You will be modifying these squares in order to nest, so you will need an extra square to make a template and a cutting tool. Kami is a good choice. Heavier paper could be problematic.

We probably will not finish all 6 of the nesting triangle box bottoms during class, but you will know how to complete the project.

✔ 8 pieces of 3x3 inch (7.5x7.5 cm) square papers
✔ To show contrast between heart and wreath, select paper one side color, reverse side different contrasting color; any color combination of the following:
• 8 pieces all one color
• 8 pieces each different colors
• 4 pieces of color A + 4 pieces of color B
• 2 pieces of 4 different colors
✔ 3 inch (7.5 cm) square makes a wreath diameter 6.75 inches (17 cm)
✔ Thin and crisp weight such as kami, harmony, paper backed foil or duo works well
⊘ Do not use thick, slippery or springy paper because wreath may fall apart
✔ Bone folder to flatten creases after assembling the wreath

This model is best with a large sheet of kami (9" to 12") (metric: 24cm to 30cm). No other supplies are needed.

This model was designed and developed using squared up white typing paper, but as you'll note from the pictures, any two toned paper will work as well. The pictured rabbits were folded form 6in Kami, but 12in paper is recommended for this class. Best results are achieved with thinner paper.

• One 6-inch (15 cm) sheet duo-color kami for the bird
• One 6-inch (15 cm) sheet heavier paper (e.g. Tant) for the toad - kami will also do.
Tweezers, bone folder or similar for one fold inside the bird's head. A bone folder could come in handy if you are folding the toad from Tant paper.

Hexagon with 8x8x8 hex grid, about 8" (20cm) wide.
Thicker paper such as copy paper, Tant or Elephant Hide is preferred, though Kami will work, too.
A pointed folding tool or toothpick will make folding this model easier.

Square origami paper, either 6 or 8 inches (15 or 20 cm).

One sheet of kami paper. 6 inch (15 cm) or above (recommend 9 inch or 24cm)

Dollar bill or similar paper currency or paper substitute. Please avoid the UK or Canadian currency with plastic inserts. You also can use paper rectangles. 2.61 x 6.14. It does not have to be exact.

Foil, Astrobrites, scrapbooking paper are all fine. Kami is a bit thin, but acceptable.

The Double Tetrahedron unit (largest red model) is made with 2"x11" (5cm x 28cm) strips for the outside strips and 1-3/4" by 11" (4.5cm x 28cm) strips for the inside unit--12 of each strip. Astrobright weight paper (24 lb/89 gsm) is recommended for the double unit.

You will need scissors and clips. Some kind of pointed thing—a toothpick, a bamboo skewer, the pointed end of a bone folder, is useful for opening up the pockets. And you can have a string available to hang it!

One square of standard origami paper, at least 6” (15cm); less experienced folders should probably use larger paper (such as 8” or 20cm).

1 piece 10 inch (25cm) duo color kami

The Letterfold is made from one sheet of 8.5x11 inch US letter paper, or any sufficiently-long and not-too-skinny rectangle will also be fine (a half-square, 2:1 proportion, e.g.) --- The Picture Frame is made from one square. If you use a 6" (15 cm) square, your picture-space will be 2 5/8" (6.66 cm) across.

Bring to class a hexagon cut from duo kami-weight paper with a point to point diameter of at least 9 inches (23 cm). Check YouTube for videos on cutting a hexagon from a square or rectangle.

Helpful also: Skewer or toothpick, a bone folder (or old credit card) for crisp folds.

3 sheets of kami, from 6" to 10:" (15-25cm)
Duo color is prefered

8 sheets of paper. 3 inches/7.5 cm.

Students will need 3 square pieces of paper. Optionally they may have at the ready an x-acto knife, a cutting board (if they wish to make cut-outs), a compass (if they wish to appreciate the constructions we will be doing) and a pen or pencil of choice (if they wish to trace the patterns we will be constructing.

6 inch (15cm) paper gives a 6 inch model.
8 squares for one star and another 8 squares for a second star.
Solid color kami looks good, duo not necessary, prints often too busy.

12 squares of patterned paper. The less symmetric the pattern the better it will look (see photo of sample paper). Note that only one side of the paper will show. Paper that is a similar weight to kami is a good choice. 7.5 cm (approx 3 inch) paper is a good size, but larger will work fine.
