Paper & Grain
Eight guided lessons move from a first fold to simple kites, folded letters, paper-cut shapes, and square-base studies.
Follow each step and its diagram. Bring the controls card up when you want to read, or move it down to give your paper more room.
Fold, cut, and draw
Close your iPhone Duo to fold the paper.

The device itself is your folding control. Follow a lesson or explore Free Fold, with cutting, drawing, and touch controls for iPhone and iPad. There’s no timer and no losing.
Every lesson and Free Fold are free. Optional tips support the app. No ads, tracking, or subscriptions.
A sheet of paper. Three ways to play.
Warm wood, softly textured paper, and simple tools. Turn the sheet in 3D to see what’s happening beneath a fold.
Fold
Line up the paper with the center guide, then close your iPhone Duo to make a crease. You can also pinch a crease or pull a corner with touch controls.
Cut
Try a paper-cut shape. Fold the sheet, make a cut, and unfold it to see the result.
Draw
Add light pencil lines to your paper. Use Undo and Redo to revise your drawing.

Free Fold leaves the next move to you. Fold and unfold, turn the paper over, cut a new shape, or add a few pencil lines.
Save editable sheets in your gallery and come back to them later. Undo a crease, try a different direction, and keep exploring.
