The paper models I have published require precision. Carving (or Scratching?) eases to make perfect folds.
A summary is shown in the image.
Step 1: Tools You Need and Preparations
- A cutter
- Crease Pattern
- Blank sheet of paper
- Transparent surface (eg. glass table)
- Light source (eg. desk lamp)
- Adhesive tape
Step 2: Carving
Use the back of the cutterblade and carve the sheet of paper with light pressure.
The result should look like in the second picture.
Step 3: Precise Folds
Therefore precise folds should be no problem.
