See usable box types
Look for 2 mm single-wall corrugated board. Lay the full-size template on a flat panel before cutting.
- Amazon or delivery boxUse a flat side away from tape, old folds, and crushed corners.
- Grocery shipping boxChoose a clean, dry panel with one wavy layer and no ventilation holes in the cut area.
- Clean pizza boxCheck the lid for one wavy layer and matching thickness. Use an area free of grease and moisture.
- Small moving boxLook at the edge first. Use it only if it has one wavy layer and matches the kit thickness.
Craft knife & matUse a mat under the board while cutting.
Pencil, ruler & scorerUse a blunt scorer for folds and calipers to check board thickness.
A4 templatesPrint at 100% and check the 100 mm ruler before tracing.
White PVA glueUse a thin coat and test the bond on an offcut.

Check the cut edge. Look for one wavy layer between two flat liners. The whole blank needs a flat area of 104.48 × 76.71 mm. Check the board →

Try the corner fold on a scrap of the same board. Use a blunt scorer and keep all six creases on the connected blank.

Dry-fit the seam and check both feet against a matching roof slope before gluing.
