Felt has a weight that paper does not, and this Happy Halloween pennant flag uses it well. It hangs flat, it holds its shape, and it does not curl at the corner by the second week of October. The greeting is the point: a Happy Halloween banner says the thing outright, so one flag finishes an entryway that would otherwise need three decorations to feel intentional. Hang it above a mantel, over a bar cart, on a kid's bedroom door, or at the end of a hallway. Because it is felt rather than printed card, it folds down at the end of the season and comes back looking the same, which is the quiet argument for a felt pennant over a paper one.
How do you hang a pennant banner? Pennant banners hang from their top edge or from attached ribbon, and removable adhesive hooks, push pins, or small nails are usually enough to hold a felt or paper pennant. They are typically displayed at eye level on a wall, above a mantel, or across a doorway.
