Washington (CNN) -- Think of pop-tops, and a soda can might come to mind. But Sister Rosemary Nyirumbe sees pop-tops as a way to help hundreds of women in Gulu, Uganda, start a new life. Nyirumbe sells women's purses made out of the aluminum tabs, and so far she has sold more than 500 purses for about $3,000. All of the proceeds go to the people who made them -- her students at the St. Monica's Girls' Tailoring Center. Eight years ago, Nyirumbe started the school in Gulu to help poor young girls and women caught in the middle of the decades-long Ugandan civil war. Many of the women had become mothers after they were abducted and raped by rebels in the Lord's Resistance Army. Nyirumbe's school feeds and rehabilitates more than 300 mothers and their babies each year. It also provides free medical care and teaches the mothers valuable life skills, such as sewing, cooking and cleaning.
