Here’s a simple approach you can try for larger letters:

1. Plan & template: Choose a font, size, and print or draw your letter outlines.
2. Transfer the outline: Tape the template to foam and trace, or pin through the paper to mark the shape.
3. Cut slowly: Use a sharp craft knife with light, repeated passes. If you use a heated cutter, follow the tool’s instructions and work in a well‑ventilated area.
4. Refine edges: Lightly sand with fine‑grit sandpaper to smooth curves.
5. Seal the surface: A thin coat of water‑based primer or diluted white glue can help reduce flaking.
6. Decorate: Brush on acrylic paint, wrap with paper, or add glitter using water‑based adhesive.

Testing cuts and finishes on a scrap piece first can help you dial in your technique.

Sizes vary by style, but on this page you’ll see options that include:

• Small to medium letters: Around 4 inches tall for crafts and signage.
• Larger letters: Around 12 inches tall for displays and decor.
• Assorted packs and stickers: Mixed heights and large alphabet stickers for posters and scrapbooking.

Helpful tips:

• Check both the height and the thickness listed in the product description to make sure they fit your project.
• Consider viewing distance: the farther away the audience, the taller the letter generally needs to be.
• If you need a very specific size, you can trim or customize foam pieces using craft tools.

You can locate them a couple of ways:

• Online or in the app: Search “foam letters,” then use filters for size, color, and material. Check availability for pickup, delivery, or shipping in your area.
• In stores: Look in the Arts & Crafts section—often near paper crafting and stickers.
• Check details: Read the product description for letter height, thickness, and pack count to make sure it matches your project.
• Stock varies: Selection can differ by location and time. If you need larger quantities, consider multi‑packs listed online.

If you’re planning a specific display, measuring your space before you shop can make choosing sizes much easier.

Lightweight foam letters can be displayed a few ways, depending on your surface and how temporary you want the setup to be:

• Temporary walls: Use low‑tack mounting putty or removable wall strips designed for painted surfaces.
• Posters/boards: Apply small dots of foam‑safe double‑sided tape or a thin layer of water‑based glue.
• Banners/garlands: Thread fishing line or ribbon through discreet anchors glued to the back.
• Freestanding displays: Insert toothpicks/dowels into the base and into a foam stand.

Always test on a hidden spot first and avoid solvent‑based adhesives, which may melt foam. Clean, dry surfaces generally help adhesives stick more reliably.

To keep foam intact and get a clean finish:

• Use water‑based paint: Acrylic craft paint is a common choice. Avoid solvent‑based sprays that can melt foam.
• Seal first (optional): A light coat of water‑based primer or diluted white glue can help smooth pores and reduce flaking.
• Apply thin coats: Several light layers with drying time between coats can reduce streaks.
• Detail carefully: Use soft brushes or foam applicators around edges to minimize tearing.
• Finish gently: A water‑based clear sealer can add durability if needed.

Testing your paint on a small scrap first can help you confirm compatibility and sheen before finishing all your letters.
