(NECN/NBC News: Natalie Swaby, Seattle) – A Seattle woman has been making superhero capes for kids who are fighting cancer and other diseases.
Now she's working on capes to send to the children hurt in the Boston Marathon bombings.
Robyn Rosenberger believes this world is filled with superheroes.
"It says super, pow, slam, zap," Rosenberger said
She's made it her job to empower them -- especially at a time like this.
"I have definitely thought about Boston a lot,” Rosenberger said. “ I definitely think about the kids."
She thinks about the bombings that killed three people, including 8-year-old Martin Richard.
"We lost something really great and what I really thought about during that time is his sister you know she is still here," Rosenberger said.
From Martin's sister, to every child hurt in Boston on Monday.
"I want them to strap their cape on and fly," Rosenberger said.
She never planned on becoming a seamstress to superheroes.
"This is my tiny superheroes cape, Super Rory," she said, describing the cape she started with, for her son.
"Then my dog needs one."
Puddles got her cape. Then Rosenberger’s handy work took a turn.
"While I was sewing them I was reading this blog about this girl named Brenna and I was like, 'Oh my gosh Brenna needs a cape,' " she said.
Baby Brenna has a rare skin disease. Robyn reached out to her family in Illinois.
"To me it is like of course I am going to send you a cape because you are a tiny superhero."
Word began to spread among families who know what it means to fight.
"Every day, they are going to the doctor and they are hearing this and this and this and we need to tell them something positive," she said.
She does it by sending them something powerful.
It's made these kids smile.
And she hopes it reminds Boston's young superheroes to smile too.
