This is called an accordion fold because if you pull the vertical edges in opposite directions, the poster unfolds like an accordion. Keep in mind that folding any poster creates creases in it. This is an option if you want to mail some sort of poster as a brochure, but it’s not recommended for collectible posters or art prints.
This is called a letter fold because it’s the typical way you fold a letter to mail it. It’s also known as a trifold. You can fit a poster folded this way into a large envelope if you want to mail it.
Moistening the folds helps relax the fibers in the paper to flatten out the creases more. However, it’s very important you don’t use a dripping wet paper towel or you might damage your poster. Make sure to move the iron back and forth over the creases constantly. Don’t let it sit in 1 place or you might burn the paper. You can use this to turn folded things like brochures and maps into artwork to frame and hang on your wall.
To roll everything up super carefully, start by creating a large roll about 1/3 of the way up, then gradually make it tighter and tighter until the roll can fit inside a poster tube. You can check this while you work by comparing the diameter of the roll with the diameter of a poster tube’s cap. Secure the roll with 3 pieces of masking tape at even intervals on the outside of the kraft paper when you’re finished rolling. Stick the rolled poster and kraft paper inside a cardboard poster tube to protect it from creasing.
If the poster is still curling when you try to lay it flat, repeat the process until you can lay it flat.
If the poster still doesn’t stay flat after being weighed down for 24 hours, repeat the process. Try using heavier objects in the corner if the poster is stubborn. To hang a poster without a frame, you can use double-sided tape on the back of the poster that does not damage paint. [7] X Research source Put a transparent tape on the corners of the poster.

You can ship a poster this way with the USPS or a private carrier like UPS or FedEx. Tape a piece of paper or stick a printed sticker with the mailing address and postage to the outside of the bag to ship it. If you’re sending the poster as a gift, fold wrapping paper around the plastic bag and tape it in place for a nice finishing touch!
Make sure you use a cardboard tube that won’t bend easily. Cardboard that’s at least 6 mm in thickness is a good choice. Stick some scrunched up bubble wrap in each end of the tube if there’s room. Place a shipping label and some “FRAGILE” stickers on the outside of the tube to ship it.
