NEW YORK (WCBS 880) — The country’s biggest flagmaker, Annin Flagmakers in Verona, N.J., has taken on one of its biggest jobs ever.

With the gentle touch of surgeons, four seamstresses are delicately repairing a tattered American flag and trimming the frayed edges, WCBS 880’s Peter Haskell reported Wednesday.

But it isn’t just any flag. It’s the national 9/11 flag — the flag that flew above ground zero in the days after the terror attacks.

Every flag is a symbol, but Annin Vice President Bob Caggiano told WCBS 880 this one is special.

“I think this symbolizes Americans’ rebound or birth from 9/11,” said Caggiano.

The flag is currently patched with flags from other tragedies, but it will eventually be restored to its original glory.

Italian immigrant Franca Tanelli is proud to be one of the seamstresses repairing the flag.
