1. The End of the "Curling" Banner
We've all seen it: a cute banner that starts curling up at the corners halfway through the party. This happens because the paper is too thin to support its own weight.
The Fix: Never use standard 20lb printer paper. For the base layer of your banner (the flag), you must use Cardstock of at least 65lb (176gsm), preferably 80lb or higher. Check out our paper guide for specific brand recommendations.
2. Anatomy of a Pro Banner (3D Layers)
To get that "expensive" look, stop printing the letter directly on the flag. Build it in layers:
- Base Layer: The flag shape (Scallop, Triangle, or Swallowtail).
- Middle Layer: A smaller shape in a contrasting color or Glitter Cardstock.
- Top Layer: The Letter itself.
The Secret Ingredient: Don't glue them flat! Use 3D Foam Dots between each layer. This creates shadows and depth. We explain exactly how to use these in our adhesives guide.
3. Suspension Engineering: Eyelets vs. Holes
If you just punch a hole in paper and pull a string through it, the paper will eventually tear. Plus, the flags often spin around and face the wall.
The Pro Solution: Set a metal Eyelet (Grommet) in each hole using a tool like the Crop-A-Dile. This reinforces the hole so it never rips. Use a wide Chiffon Ribbon or satin ribbon instead of thin string—friction keeps the flag facing forward.
4. Cutting Techniques: Flags & Circles
Cutting 15 identical flags by hand is tedious. For straight-line banners (triangles/swallowtails), use a Guillotine Trimmer to cut multiple sheets at once.
For circular banners or scalloped edges, nothing beats a manual Lever Punch or a cutting machine. (Read more in our cutting tools guide).
5. Choosing the Right Fonts
For banners, legibility is key. You want guests to read "HAPPY BIRTHDAY" from across the room. Avoid thin, spindly scripts that disappear at a distance.
Go for bold, thick display fonts. If you need inspiration, check our list of best free fonts and look for the "Display" or "Bold" sections.

- How far apart should the flags be?
- We recommend leaving about 1 to 2 inches of space between flags on the ribbon. This allows them to move slightly without overlapping when the banner hangs in a curve.
- Can I use hot glue for banners?
- Yes, you can use hot glue to attach the ribbon to the back of the flags if you don't want to punch holes. However, this makes the banner rigid and harder to fold/store.
- What is a "Shaker" banner?
- A shaker banner uses a layer of acetate (plastic) to trap sequins inside a window on the flag. It's a fun, interactive trend. You can learn more about layering with acetate in our cake topper guide.
