Assembling tiled pattern sheets

1. Lay the sheets out (top-left, across, then down)

Each sheet has a row/column code in the corner (1A, 2A… / 1B, 2B…). Starting from 1A at the top-left, go right, then to the next row to see the whole layout.

Katagami prints an assembly map (a mini diagram) on the first guide sheet, and each tile also shows its neighbours (“→ to 2A”, “↓ to 1B”). Lay everything out on a floor or table first.

2. Overlap the join

Adjacent sheets are made to overlap by about 10 mm. When overlapping, line up the dashed content border and the grid lines exactly.

1. Lay the right-hand sheet on top of the left one, over its border.
2. Slide it until the grid and the drawn lines run continuously, then fix in place.
3. Holding the join up to a window or bright light makes it easy to see the lines align.

✏️ Trimming a few mm off the overlapping margin first gives a flatter, neater join.

3. Tools and order

• Tools: masking tape (easy to redo) / glue stick / clear tape.
• Order: join one horizontal row first, then join the rows top-to-bottom — this keeps errors from adding up.
• Once it's all joined, cut along the outer cutting line (solid).

4. Common mistakes

• It drifts and the last sheet won't match: you must overlap the 10 mm margin, not butt the edges together.
• Everything is slightly small: likely it didn't print at actual size — check the printing settings and calibration box first.
• Unsure of the order: use the assembly map and the corner codes on each sheet.

Frequently asked questions

Do I butt the edges or overlap them?

Overlap. Adjacent sheets share about a 10 mm overlap, so layer them until the lines run straight. Butting the edges makes the whole pattern smaller.

Should I trim before joining?

Trim a few mm off the margin of the sheet that goes on top to reduce the step. Cut the actual cutting line only after everything is joined.

There are so many sheets.

Use a smaller finished size, or start with the pieces that need fewer sheets. Katagami shows the sheet count before you print.
