mix and match fabric flag banners. Flags slide on the flag line so you can space them as far a part as you want, add flags, remove, flags, etc. High quality - double-sided, top-stitched to hold shape even when washed, made with black out fabric insert to give durability and allow it to be hung in direct sunlight.
