You need one uncut sheet of printer paper, short edge at the top. No scissors, tape or clips. Measurements are rounded to the nearest ⅛ inch, as in the app.

Fold it step by step
- 01
Crease down the middle
Fold the sheet in half the long way, press hard, and open it again.
Every fold on the Needle lines up with this crease, so make it sharp.
- 02
Fold the top corners in
Bring the top-right corner down so the top edge lies along the center crease.
Same start as the Dart.
- 03
And the left corner
Same on the left side.
The edges meet on the crease without overlapping.
- 04
Edges to the middle
Fold the slanted right edge in to the center crease.
The point gets sharper.
- 05
Left edge too
Fold the slanted left edge in to the center.
Keep the tip crisp.
- 06
One more time
Fold the right edge in to the center again. It is thick now, so press firmly.
This extra fold is what makes it a Needle.
- 07
And the left, again
Fold the left edge in to the center to match.
Run a fingernail along both folds.
- 08
Fold it in half
Fold it in half along the center crease with the flaps inside.
Squeeze it flat from nose to tail.
- 09
Fold down the first wing
Fold the top layer down on a slant: ¼ in (0.5 cm) from the center fold at the nose, ⅜ in (1.0 cm) from it at the tail.Fold the top layer down on a slant: 0.5 cm (¼ in) from the center fold at the nose, 1.0 cm (⅜ in) from it at the tail.
Keep the body strip thin so most of the paper goes into the wings.
- 10
Turn it over
Flip the plane over.
Nose stays pointing away from you.
- 11
Fold down the second wing
Fold this wing down on the same slant as the first one.
Hold them together to check.
- 12
Open the wings and bend the tail up
Open the wings, then bend the back edge of each wing up about 3 mm.
Check the shape
A fast climb followed by a nose-down drop can be a stall rather than a loop. Watch the whole path and repeat the release before adjusting the bends.
The different back-edge bends are intentional for this stunt. Unequal wing creases are still a folding error; fix those first.
First flights
Launch:
The trim is the stunt. The last step sets it: Open the wings, then bend the back edge of each wing up about 3 mm.
Loops need height and room. Throw upward in an open space, and watch the whole path: a climb that ends in a nose-down drop is a stall, not a loop. If it stalls, check that the two bends match before making them bigger.
If it misbehaves
- Dives straight down
- Release level, then bend both back edges up a hair.
- Climbs, then drops
- Flatten those bends a little; throw nearer level.
- Always turns one way
- Compare the wings first. Then bend the edge on the inside of the turn down, or the outside edge up, very slightly.
The app can fly this plane in a simulator. Its distances and paths are simulation output; this page makes no claim about how far a hand-folded Comet will fly.
More needle noses
A third pair of edge folds narrows the dart further. The nose gets thick quickly, so these reward careful alignment more than force.
