DRACUT -- When event organizers ordered 1,200 Boston Strong T-shirts for the Boston Marathon recovery fundraiser on Saturday, they figured several shirts would be left over.
Their prediction could not have been further off.
Only 90 minutes into the four-hour fundraiser for Dracut native Roseann Sdoia at Carbon Colors, every shirt was off the shelf.
"Just unbelievable," said Brian McMahon, a Lowell resident who knows Sdoia from working with her mother, Rose. He helped promote the fundraiser, which is sending all proceeds to Sdoia, who lost a leg above the knee in the Boston Marathon bombings.
"It was just overwhelming," McMahon added. "People were buying five, 10 shirts at a time, and we sold out in no time."
After the 1,200 shirts were sold, 500 additional shirts were ordered for prepaid pick-up on May 4 at 9 a.m. At that time, Carbon Colors will sell 500 more shirts for anyone who did not preorder one.
The shirts, which are royal blue with yellow "Boston Strong" lettering and a yellow ribbon over the second Boston "O," cost $20.
About $35,000 is expected to be raised for Sdoia through this T-shirt fundraiser, McMahon said.
"It's never going to be enough for her, with all her costs, but this will help in some way," he said. "It's a way to start the healing process. Every time you looked up, someone was hugging somebody.
"The whole community was amazing, wanting to help in any way possible," he added.
Ann Tinnirella, owner of Carbon Colors, said the printing business at 1274 Lakeview Ave. was originally planning to send the proceeds to any Boston Marathon victim. But once she found out that Sdoia was a Dracut native, Tinnirella thought that Sdoia would be a "great recipient for the money."
"It was an amazing response. We had bumper-to-bumper traffic down the street for four hours," said Tinnirella, who added that Carbon Colors came up with the logo. "It was all for a good cause that came out of an unfortunate thing that happened."
She also thanked WCAP 980 AM and the Dracut police, fire and EMS for spreading the word about the fundraiser. WCAP did a live broadcast from the event.
The T-shirt mania has even spread across the country. McMahon, who also pointed to an article in The Sun last week advancing the event, said they have gotten calls from people in California and North Carolina who want the shirts.
After they sold out on Saturday, a woman came down from Portsmouth, N.H., and wanted four shirts for a road race on Sunday. When McMahon broke the news that they were only taking preorders, she almost started to cry, he said.
"We ended up selling her the shirts that we were wearing," McMahon said. "So I don't even have a T-shirt today. Everyone wants them."
A fund for Sdoia started by longtime friend Christine Rousseau Hart had already raised more than $310,000 as of Monday afternoon. The goal is $750,000.
Sdoia, who lives in Boston, was recently transferred to Spaulding Rehabilitation Hospital in Boston, McMahon said.
"Everything is moving ahead right now," he said. "She has a great attitude. She's moving around, which is a real big step in the recovery."
