Sending a letter or organizing documents often requires a clean, sturdy envelope. You do not need to run to the store every time you run out of supplies. You can easily craft your own professional mailers at home using basic tools.
This step-by-step video demonstrates how to make an envelope out of paper using just a sheet of paper, scissors, and craft glue. The result is a crisp, official-style envelope suitable for business letters, greeting cards, or small gifts. Standard office printer paper works well, but you can also use colored paper or light cardstock for extra durability.
The process is simple and takes just a few minutes. First, measure and cut your paper to the right size. Next, score and fold the side flaps inward to create sharp edges. Apply a thin strip of glue along the bottom seams and press firmly. Let the glue dry completely before inserting your contents to prevent any paper sticking.
Watch the full tutorial below to see the exact measurements and folding steps. Once you learn the basic technique, you can easily adapt the size to fit any letter or card.
