Make a Rounded-Flap Paper Envelope

WHAT TO GATHER

Your starting kit.

Plain paper or cardstock suited to the folds described below
A ruler, pencil, and scissors
Paper glue and scrap paper for protecting the work surface
A blunt folding tool for scored creases

STEP 01

Measure and prepare

Center a blank A6 card on a paper rectangle roughly 240 by 220 mm.

STEP 02

Lay out the construction

Fold both sides across the card with a small overlap, then fold the bottom up. Remove the card and round the top flap corners with scissors.

STEP 03

Join and shape

Glue the bottom flap only where it overlaps the side flaps. Slip the card back inside after drying and fold the top down.

STEP 04

Check the result

Keep glue away from the inner pocket; test your paper dimensions with scrap before cutting decorative stock. Let glued joints dry according to the adhesive instructions. Compare the finished shape with its intended use: moving parts should move freely, open pockets should remain open, and supporting folds should sit level. Trim only a little at a time if a paper edge catches.

STEP 05

Finish and keep

Remove temporary pencil guides with a clean eraser where the paper allows it. Store the finished piece somewhere dry and avoid putting pressure on raised or rolled details. Keep your first scrap-paper version nearby if you want to change the dimensions next time.

Before you begin.

Can I change the paper size?

Yes. Make a scrap version first and keep the same fold sequence. Where a piece wraps another object, measure the actual object and add space for its thickness instead of enlarging only one dimension.

What should I check before beginning?

Keep glue away from the inner pocket; test your paper dimensions with scrap before cutting decorative stock.
