Like many businesses before, this one started by 6-year-old Darcie and 4-year-old Coco started with a problem, a mask problem.
"Our mom didn't want us losing them or dropping them on accident," Darcie Hayes said.
That's when inspiration struck.
"Hey how about we start making Fancy Faces."
The sisters started making lanyards with beads and accessories so that you can wear your mask like a necklace when it's not on. Fancy Face was born.
The sisters come up with the designs, with a little parental help.
"Our mom helps us out just a little bit. We really, really love doing it," Darcie said.
So far, they've given away and sold around 170 of them on Facebook, with all the money going to the Boys and Girls Club of Oklahoma City.
This weekend, they'll be taking their mask lanyards to market, Vintage Markets Days in Oklahoma City.
"Darcie and Coco Hayes are my youngest vendors by far," said Erica Parker, Vintage Market Days owner.
Parker has been hard at work getting things ready for Vintage Market Days this weekend.
She's happy to have Darcie and Coco manning one of the 100 booths, proof that the entrepreneurial spirit has no age limit.
"It fixed a problem that we had and made it appealing and trendy to people, and I think that's amazing," Parker said.
You can catch Darcie and Coco this weekend at Vintage Market Days. It's a different location this year, at Chisolm Creek in Oklahoma City off Pawnee Dr.
Part of the proceeds go to charity.
