Finishing Options for 4x21 Banners
- Print only: edges trimmed to size, no grommets. Good for mounting flat on a board or frame.
- Grommets only: grommets along the edges for hanging with ties, hooks, or bungee cords.
- Hemmed edges plus grommets: edges folded over and reinforced, with grommets for hanging. The sturdiest choice for outdoor use.
Optional on any size: pole pockets (sleeves for a pole or rod) and wind slits (small cuts that let wind pass through on fences and outdoor walls; single-sided banners only).
