Key Takeaways
- Trim standard printer paper into a square, about 8.5 x 8.5 inches, for easy folding.
- Fold the square diagonally to form a triangle, then fold the left and right corners inward to meet at the center.

Gather Paper and Tools for Your Envelope

Before you start folding, gather all the materials you’ll need to make your envelope. Start with standard printer paper—either 8.5 x 11 inches or A4—and trim it to a square if you want an origami-style envelope.
You can also use patterned paper or DIY paper with printed designs for a decorative touch. Just keep in mind that thicker paper over 120 gsm might be harder to fold neatly.
Next, assemble your tools: a ruler and pencil for marking folds, scissors or a paper trimmer for cutting, and a bone folder or the back of a spoon to create crisp creases.
Don’t forget adhesive options like a glue stick, double-sided tape, or a strong permanent glue to seal your envelope securely. Scoring fold lines lightly will help keep your paper from tearing.
Fold Your Paper Envelope Step-by-Step

Start by trimming your printer paper into a square—8.5 by 8.5 inches works well—and position it like a diamond on your workspace. Fold the bottom corner up to meet the top corner, creating a triangle.
Next, fold the left and right corners inward so their tips overlap slightly at the center; these form the side flaps of your paper envelope. Now, fold the bottom flap up over the overlapping side flaps about half an inch to create the envelope pocket. Press firmly to crease.
For custom envelopes, add glue or double-sided tape along the inner edges of the side flaps before folding the bottom flap up to secure everything in place. This step guarantees your paper envelope holds its shape and contents safely.
Seal and Customize Your Paper Envelope

Once you’ve folded and secured your envelope flaps, give the seams a firm press for 30 to 60 seconds. Then, let the adhesive set for at least 5 to 10 minutes to guarantee a strong seal.
To close the top flap neatly, use a decorative sticker, washi tape, or a sealed label. This also lets you customize your envelope with a stylish touch—perfect for party invitations.
For mailing, reinforce the flap inside with clear packing tape and add a white mailing label for address clarity. You can further customize your envelope by adding rubber stamps, hand lettering, or a glued paper band.
Lining the envelope with thin contrasting paper or sealing edges with archival glue helps protect contents and prevents tearing. This way, your party invitations arrive in great shape.
