Square Gusset Bag gift box project / LETTER
A good fit for your idea?
Letter and A4 preserve the component dimensions. Choose the sheet you will print, not a different object size.
Materials and construction
Plain paper for a first trial, a ruler, scissors and a blunt scoring tool; adult help for internal cuts.
Before making a batch
Measure the 50 mm reference and at least two named panel dimensions.
Assemble an empty plain-paper trial; record closure, seam, clearance and material behavior.

Front and back: 64 x 91 mm; two 20 mm gusset panels; flat base nominally 64 x 20 mm.
Opposed bottom flaps project 12 mm each and overlap by 4 mm. Top fold-over band: 20 mm; side seam: 8 mm.
From file to finished page
- Cut the net with all four attached bottom flaps. Score panel divisions, gusset centers, bottom hinges and the top band.
- Fold the side panels inward on their middle lines, then reopen to the rectangular cross-section. Glue the 8 mm side seam inside the first panel.
- Fold the two narrow dust flaps inward first. Fold the front and back bottom flaps over them; apply adhesive only where their final 4 mm overlap lands.
- Let the base dry supported on a flat surface. Gently close the gussets using the bottom diagonal creases without crushing the base.
- Fold the 20 mm top band down after loading only an expendable, dry, lightweight trial item. Verify closure and tearing before selecting final paper. This is a display pouch, not a carrying or shipping bag.
Printing and use notes
Nominal drawing dimensions are not a tested usable-capacity, load, mailing, food-contact or archival specification.
Do not place valuable, wet, hot or breakable items in an unreviewed paper prototype.
