Mary Jorgensen, 18, said after she joined the club and learned how to knit, her mother, who had always been a fan of crocheting, wanted to learn.
"She became obsessed with [knitting]," Jorgensen said, laughing.
The hats make for good personalized gifts: "I love to pick out the colors," Jorgensen said.
Last year, Williams was visiting a friend in North Carolina whose grandfather wasn't expected to live much longer. Williams instructed her friend's family members to each knit several rows of yarn for a hat.
"Everyone worked on it and he loved it," she said.
The group helped Hannah Warner, 14, make close friends during her first year of high school.
"I actually made [a hat] I was going to donate, but I kept it [because] I liked it so much," she said.
The group often sells hats and holds fundraisers to purchase yarn.
On Tuesday, the girls dug through a box of brightly colored hats, some finding the first one they made as a club member. Williams said that after she graduates this spring, she hopes others will continue the group.
"We definitely will," other members said at the same time. Williams smiled, and put both thumbs in the air.
