A South Carolina kindergarten teacher had her students make peanut butter and jelly sandwiches for Washington, D.C., rescue workers. A North Carolina man bought lemonade for $100 from kids raising money for the Red Cross.
People came in droves to a Seattle flower vigil. Christians, Jews and Muslims stood side by side in services across America to show their solidarity.
Around the country Monday, Americans continued to stand united.
In Rock Hill, S.C., teacher Jamie Laymon directed the 24 kindergarten children in her class to make PB&J sandwiches to send to D.C. rescuers. All told, students at the Sylvia Circle Elementary School made 500 sandwiches, which they shipped with a note.
"We decided to make this for you because peanut butter and jelly sticks together like you guys have stuck together to help America," the students wrote.
Laymon said doing something simple to help out was a better way to address the situation with such young children than talking endlessly about Tuesday's terrorist attacks – which many adults can't even grasp.
"I thought I could tell them how important our flag is and that they are Americans," she said. "They know that people were hurt and that a lot of other people are trying to help them."
Just to the north, a man reportedly bought a cup of pink lemonade for $100 at a stand in Charlotte, N.C., where youths raised $1,000 in two days for the American Red Cross' efforts to aid the rescue effort at the World Trade Center and the Pentagon.
The children's parents helped them make lemonade and punch and set up the stand. Many neighbors came to the fundraiser, lining up at the stand. Some gave money without even taking a drink.
Nine-year-old Julia Devita, who was helping at the lemonade stand and whose second cousin is among the missing at the World Trade Center, said she took all the money she saved for a shopping spree and donated it to the cause.
Rallies and vigils around the country were another way citizens chose to unite.
In Seattle, a flower vigil was extended to last through Monday because of the sheer numbers of people who turned out at the Seattle Center to lay flowers next to the building's fountain.
The vigil was originally planned as a three-hour ceremony Saturday but more than 30,000 people showed up at the center's International Fountain by late Saturday night to place flowers at the water's edge. Thousands more turned out Sunday, leaving 500,000 flowers.
In Augusta, Maine, hundreds of state residents came together, formed a ring and held hands in a Capitol Park rally Sunday. They sang the national anthem and prayed. In Lewiston, Maine, 1,500 people carrying American flags stood shoulder to shoulder in Kennedy Park on Sunday, then later lit candles.
Other vigils and ceremonies were held around the country. People waved American flags, chanted "U-S-A" and wore red, white and blue.
Some of the ceremonies – like one at the Tucson Convention Center in Arizona and another at St. Mark's Episcopal Cathedral in Seattle - had Muslims, Christians and Jews in attendance, side by side, standing together as one people.
"This is just a wonderful expression of solidarity," said the Very Rev. Robert V. Taylor, dean of St. Mark's Cathedral.
In Kent, Conn., an artist has designed a sculpture showing a man and woman embracing, their figures rising above the Manhattan skyline. Ken Memoli will cast about 500 or 600 of the commemorative sculptures, which will sell for about $125 apiece. More than $100 from each sale will go toward the relief fund.
Some citizens have painted the American flag on the roofs of their houses to show their patriotism and unity. Near St. Louis, Mo., Molly Pointer and her brother spent four hours painting Old Glory on the roof of their home, in the suburb of Florissant.
Children in New Hampshire held bake sales and car washes to raise money for the rescue. Volunteer New Hampshire firefighters stood at a busy intersection in Warner and asked motorists to put money for the disaster into a fireman's boot.
In Nebraska red, white and blue T-shirts are being sold for $15 through police and fire stations across the state; the proceeds are going to the recovery efforts.
Despite plummeting stocks and a bleak future in store for the industry, airline workers also came together in unusual displays of unity.
At Dulles Airport outside Washington, where one of the planes that crashed into the twin towers originated, American Airlines pilots and flight attendants gathered in the main terminal to thank passengers who were once again taking to the skies. They held an American flag and promised to carry it on flights as a symbol of strength.
Southwest pilots of one flight out of California waited at the bottom of the stairs on the tarmac to greet boarding passengers. One pilot wore a red, white and blue flag tie. Another walked up and down the aisle of the plane to talk to people settling into their seats.
Television networks have been talking about hosting an industry-wide benefit telethon Friday night to raise money for the relief and recovery effort. The goal would be to broadcast the two- or three-hour special simultaneously on as many networks and cable channels as possible. If it happens, the event would be the first of its kind in the TV industry's history.
Olympic organizers are also doing their part. They unveiled a "We Stand United" pin that they're selling to help raise money.
Even inmates are showing their patriotism. Prisoners in West Virginia are donating blood for the victims of the terrorist attacks.
