Five Paper Folds Every Crafter Uses
You will finish this able to read any paper craft instruction without stalling. Five folds cover almost everything: valley, mountain, accordion, gate, and a scored spine. Twenty minutes, five sheets of scrap paper, no project attached.
This is deliberately not a project. Learn the folds cold on paper you do not care about, and every project after this gets faster.
What you need
- Five or six sheets of scrap paper. Printer paper is perfect.
- One sheet of card stock, if you have any, for the last fold.
- A bone folder, or an empty ballpoint pen, or the back of a butter knife.
- A hard table. Folding on carpet or a cushion is why folds go soft.
Steps
-
Valley fold — the fold that makes a trough. Bring the bottom edge up to meet the top edge and press down. Hold the edges together with one hand while you sweep the crease flat with the other, working outward from the centre. If you crease first and align second, the edges never match. Look at it side-on: the crease sits at the bottom of a V. That is a valley.
-
Mountain fold — the same fold, seen from behind. Take a fresh sheet and fold it away from you instead, so the crease rises into a ridge. That is all a mountain is: a valley flipped over. Diagrams mark valleys with a dashed line and mountains with a dash-dot line, and when a diagram fights you, the fix is usually to turn the paper over rather than to fold it differently.
-
Accordion fold — valley, mountain, valley, mountain. Fold the bottom edge up about two centimetres. Flip the sheet, fold the same amount again, flip, repeat to the top. The gotcha bites here: fold against the previous crease each time, not against a mark you measured. Any error compounds down the sheet, and by pleat eight a two-millimetre drift is a visible wedge. Pinch the last fold, let go, and it should spring open like a fan.
-
Gate fold — two doors meeting in the middle. Fold the sheet in half, crease only lightly, and open it back out; that centre line is a guide, not a fold. Now bring the left edge in to meet it and crease hard. Bring the right edge in to meet it and crease hard. Two flaps meet down the middle like shutters. Undershoot rather than overshoot — a one-millimetre gap down the centre looks intentional, and overlapping flaps never will.
-
Scored spine — the fold that saves card stock. Card stock does not fold, it cracks. Lay a ruler where the fold goes and run an empty ballpoint down the line, pressing firmly enough to dent the surface without tearing it. Then fold along the dent, ridge outward. You get a clean straight spine instead of a ragged white split. This one fold is the difference between a card that looks made and one that looks mangled.
The one habit that fixes all five
Crease with pressure, not with repetition. One firm pass with a bone folder or your thumbnail beats ten anxious rubs, which only burnish and grey the paper. Work from the middle of the crease outward each time so trapped air escapes at the edges.
Fold with the grain when you can. Tear a scrap of your paper in both directions: one tear runs straighter than the other, and that straighter direction is the grain. Folds along the grain come out sharp; folds across it fight back and fluff.
One variation
Combine the accordion and the gate on one sheet and you have a basic pop-out card blank: accordion-pleat a narrow strip, glue one end inside a gate-folded cover, and the pleat springs open when the doors do. It is the entire mechanism behind most pop-up cards, built from two folds you now know.
Before you go
Keep your five practice folds on the table for a day and refold them cold, without reading anything. That is what makes them stick.
The scored spine deserves its own ten minutes — we go deep on pens, pressure and which side to fold toward in score, don't cut. For a project that puts valley and mountain to work straight away, the beginner paper star needs nothing but folds and one snip. And if you want ruled paper to practise even pleats on, the free dot grid paper pack prints straight lines for you to fold against.
