This ECONOMY Union Jack flag bunting is available in 10m lengths.
Each 6x9" pennant is unhemmed and stitched to a white cotton apron tape as standard. Each length has an additional strip of tape for tie off.
10m length - 27 pennants
So if you're ordering 100m for instance, you'll need to order 10 of the 10m lengths.
This is a cheap and cheerful option.
