To make an envelope, follow these general steps:
- Choose a piece of paper slightly larger than the card or item you want to enclose. It can be any paper such as plain, patterned, cardstock, or even wrapping paper.
- Place the paper on a flat surface with the side you want on the outside facing down. Fold the two longer edges of the paper inward about 1.5 to 2 cm and crease firmly.
- Fold the bottom flap of the paper upwards over the folded sides. Unfold, then apply glue or double-sided tape along the side flaps.
- Fold the bottom flap back up and press to adhere the sides in place.
- Fold down the top corners to meet in the middle, forming triangles. Crease well.
- Optionally, apply glue or tape to the top flaps to close the envelope securely.
This creates a simple, customized envelope suitable for cards or notes. It can also be made without glue using origami folding techniques. More detailed tutorials and variations exist, including templates and glue-free methods.
