Several members of Congress took thread and needle on Thursday to a flag destroyed in the terrorist attacks of Sept. 11.

Lawmakers joined the families of Sept. 11 victims in a flag stitching ceremony for what is known as the National 9/11 Flag.

New York native Sen. Charles Schumer (D-N.Y.) tweeted:

National 9/11 flag will come to Congress for stitching ceremony today as we begin to mark 10yr anny of 9/11

Rep. Gabrielle Giffords's (D-Ariz.) office also tweeted about the occasion, announcing to her followers that they could sew a stitch if they came by the Capitol today.

Several members of Congress tweeted pictures of themselves helping stitch together the flag that was originally destroyed in Sept. 11 and then stitched back together seven years later by tornado survivors in Greensburg, Kan.

Sen. Scott Brown (R-Mass.) tweeted:

Today I had the honor of sewing a few stitches into the National 9/11 Flag

Sen. Frank R. Lautenburg (D-N.J.) tweeted:

As 10th anniv. of 9/11 approaches, Lautenberg joins families of victims to add a stitch to the National 9/11 Flag:

According to a tweet by Rep. Carolyn Maloney (D-N.Y.), the flag-stitching ceremony was a part of a national initiative “to make @911Day biggest day of charitable service ever.”
