VOORHEES, N.J. (WPVI) -- Rebecca and Lindsay Kligerman are twins from Marlton, New Jersey.
The now 12-year-old twins were born at just 27-weeks-old, weighing less than two pounds each.
The girls spent their first three months of life at the Virtua Voorhees Neonatal Intensive Care Unit.
On Wednesday, the girls returned to that NICU with a very special gift for the tiniest patients who are now spending their first moments of life there.
The girls spent 50 hours creating the 50 handmade blankets they donated.
Their mom, Amy Kligerman, tells us it was part of project for their bat mitzvah that was all about paying it forward.
Amy says, "They decided they wanted to give back to the NICU, that means so much to us. So, it's something (the blankets) they feel is special to have from the day they were born until they are older - remember where they came from."
When they were healthy enough to go home, a nurse gave each of them a handmade blanket, and they say they still cherish it to this day.
And so today, the girls say they hope to give the preemies there now and their families a little keepsake, and a lot of hope.
