Paper craft · one sheet, no drama
One sheet of 8.5 × 11" paper, three folds, and one small cut down the centre — that's it. No glue, no stapler, no sewing kit. Just a slit that lets the whole thing pop into a tiny book.
This is the sheet laid flat once it's creased into eighths. Dashed lines are fold guides only — the solid pink line is the one spot your scissors are allowed near.
Once the slit is cut, four quick moves turn it into pages.
1 · Sheet slit down the centre
2 · Fold hot dog-style in half
3 · Push the ends in — watch it pop into a diamond
4 · Press it flat — booklet, unlocked
Bring the long (11") edges together. Crease well, then unfold.
Bring the short (8.5") edges together. Crease well.
The sheet is now creased into eighths.
You'll see one long crease down the centre and three creases running across — that's the grid in the diagram above.
Short edges together — this fold is just to set up the cut.
Start at the folded edge and stop at the halfway point (that's the pink line up top). Whatever you do, don't cut through to the open edge.
There's now one slit down the middle of the sheet, stopping short of the top and bottom edges.
Hold the short ends and push them toward the middle — the slit pops open into a diamond, like magic.
Keep the ends pushed together and flatten the whole thing down — it collapses into an 8-page booklet. Crease every fold well and you're done.
Do a practice run first — fold and cut one blank sheet, then pencil in page numbers 1–8 while it's assembled as a booklet. Unfold it flat and you'll see exactly which panel is which page (and which ones land upside-down), so your layout actually lines up once you print double-sided and refold.
Which side folds over which in step 8 flips this mapping left-to-right — exactly why a generic numbered template can't be trusted blindly. Do your own test fold.
Working in A4 instead of Letter? Same fold sequence, same steps — your panels just land at 210 × 297 mm instead.
