How to design your own pop-up cards

Anybody can learn how to make pop-up cards by following a pattern. This tutorial will teach you how to understand pop-up cards so you can design your own. There are many types of pop-ups, but to keep things from getting too complicated and long, in this tutorial I will only discuss the style known as OA (for Origamic Architecture), and limit myself to cards which are best viewed when they are opened at a 90° angle.

Would-be paper engineers have many craft book options to choose from, and though I have a few of them in my library, I find it much more helpful to learn by making — so my first piece of advice is to download a few of my pop-up cards, make them, and then come back to read the rest of this tutorial.  I recommend starting with some of these pop-ups, many of which are free.

How to Make Pop-Up Cards: Basic Tools

scalpel knife make pop-up cardsYou can use scissors for some symmetrical pop-up cards, but if you are serious about learning how to make pop-up cards you will need a scalpel knife. This type of knife is often referred to by the brand name X-ACTO. You will also need a supply of  sharp blades.

 

self healing cutting mat such as this one is perfect for cutting with a scalpel knife. Though you can protect your table by cutting over old newspapers, this will preserve the life of your blades and ensure your cuts are smooth.

 

Traditionally bone folders are used for scoring, but I find this type of embossing stylus much easier to handle. Use the finer tip for scoring. Unless it’s a tiny score line, use this tool with a ruler so your score lines are nice and straight.

It is useful to have a stainless steel ruler with non slip cork base, rather than a regular plastic ruler. Plastic is too easily dented and nicked. It can also slip while you’re trying to use it. Fold lines must always be straight, so always use a ruler!

Here is a more comprehensive list of recommended tools and materials.

HOW TO MAKE POP-UP CARDS

Cuts and Folds

heart cut and fold copyWhen making a pop-up card all folds must be straight lines.

Mountain folds look like the top of a mountain, and valley folds look like the bottom of a V — like a valley.

Cuts don’t need to be straight lines, but they must go from valley fold, across a mountain top, to the next valley fold.

How to Make Pop-Up Cards: Basic Shape #1: the Rectangle

rectangle-pop-up
The blue sides must be the same length, the red distances must be equal, and (unless you want the pop-up to stick out of your folded card) the yellow distance must be greater than or equal to the blue, and the green distance must be greater than or equal to the red.

I call this shape a rectangle, but the end result can look like anything: the Brooklyn Bridge,  a table or a chair. The heart pictured above is also based on the rectangle shape.

What characterizes the rectangle pop-up is that all the fold lines are parallel. When the card is opened at a 90° angle, the empty shape, when the card is viewed from the side, forms a rectangle (if it forms a square then that pop-up is symmetrical; you can fold it first, then cut over the fold with a pair of scissors).

How to Make Pop-Up Cards: Basic Shape #2 The Triangle

IMG_4168

Triangles (aka V fold pop-ups) can be super easy, especially when they are symmetrical like the classic beak above or the heart on the right. However, you can also design them so they slant to the side, like the dove pictured below.

folded heart

To make a symmetrical triangle you can just fold a piece of paper in half, cut a single slit from the fold, then fold the your shape at any angle.  If you’re drawing it, just make the tip converge with the main fold, and draw identical angles on either side of the main fold.This is so easy you won’t even need a template: you can just draw it freehand, or even cut it directly without drawing a thing!

Eifel Tower

The Eiffel Tower is an example of symmetrical triangles drawn with different angles. You can watch me make it here.

Asymmetrical triangles

Below are two sketches which show how the asymmetrical triangle pop-ups work — it’s much easier to understand those visually rather than with words.

A big advantage of the triangle is that it gives extra dynamism to your pop-up as you open and close the card. Look at the animated photo below. The face with the flower could easily have been made as a silhouette with a rectangle pop-up. However, since it is drawn with a triangle, as you close the card the face leans down towards the flower. Open it, and the face pulls away!Smell-flower

The triangle fold is what makes this violinist appear like she is playing the violin.

Watch out though, once you move beyond the classic bird beak and try to combine triangles on different planes they can get complicated fast, but as long as you keep your design simple triangles are easy and fun to play with when you are learning how to make pop-up cards.

How to Make Pop-Up Cards: Combining Shapes

Martini glass

Just by using and combining triangles and rectangles you can obtain an astonishing variety of shapes: the house shows a square combined with a triangle roof, and the ship is almost identical, just upside down. The martini glass is made of a square stem with two symmetrical triangles forming the base and the glass.

Simple Ship

When you design any card you’ll be making several drafts, trying out shapes and then adjusting them. To make the Phoenician ship below, for example, in my first draft I adjusted the shape of my standard ship hull (adjusting the bow). Then I added the characteristic Phoenician square sail — but it looked too chunky, so I re-drew the sail cut lines to make it look like the wind was blowing and puffing it out.

How to Make Pop-Up Cards: Create a 3D sketch

hump-day-sketch

When I start a new design, I start by imagining the shape in my head. Then I draw a very rough sketch with paper and pencil and cut it out. I use that pop-up sketch as a guide to draw the cut and fold lines on my computer. Next, depending on the situation, I add photos or illustrations to the design. When using photos, there’s often a little back and forth, I’ll need to adjust both the cut and fold lines and the images.

Don’t start a card with the graphics, always start by drawing your cut and fold lines! You can adjust your cut and fold lines to your images later, but you will waste a lot of time and ink if you start out with the graphics. First get the pop-up to work, then decorate.

Side note: this camel card is a bit of a hybrid. To make the camel stand up the card is opened at more than 90 degrees, but less than 180 degrees (if opened all the way, the camel lies flat, but at 90 degrees it doesn’t look great either). I designed it this way intentionally to make the card simple and quick to make. No need to fuss with tabs or gluing.

How to Make Pop-Up Cards: Irregular shapes

eight-with-marks

Sometimes a rectangle shape will have one part extend a little farther — for example, in this figure 8, the lower O is wider than the top 0. On the school bus the roof is higher than the front — besides these variations, theses designs are all basically simple rectangular pop-ups.schoolbus

One Step at a Time

Start simple, then add layers. If you first try to draw a complete and complex pop-up you’ll drive yourself crazy, but take it one step at a time and you can make almost anything. Start simple, then add layers. I cannot repeat this enough.layer1 layer2

Start simple, then add layers

A perfect illustration of what you can achieve by starting simple, then adding layers one step at a time is the staircase. It is an irregular shape, as explained above, with one vertical plane (orange in the illustration below) and then many horizontal planes, making the steps. This slide show illustrates how you start with one fairly simple shape (stairs), then add to it to make stairs with a landing, then add graphics for extra realism, or instead keep on adding one series of steps after another to make an Eicher-like set of impossible stairs.

 

Wield your knife wisely

VillageWhile you’ve got your knife out you may as well make a few extra cuts: the village and Statue of Liberty pictured here have extra cut-outs which contribute to the sense of depth and space. In one of my favorite cards, the Matterhorn is just a cut-out silhouette, with only the foreground hills popping out of the page. You can also, of course, get a similar effect by drawing graphics but there’s something quite special about an image made from a single sheet of paper with no visible ink.

In some cases cutting out the extra paper will remove a distracting shape, as you can see in the stork pop-up. Without the cloud you see and recognize the shape of the beak. This gives the stork an odd shadow. Cut out the shape of a cloud in the sky and you only see the stork.

Some times you might like to use that shadow. When I wanted to create the effect of a rush of birds flying out of a tree, the shadows doubled the number of flying birds.
