FARGO (AP) - Seven-year-old Mikayla Coenen has opened a card shop at MeritCare Children's Hospital, where she is finishing a round of chemotherapy.

She opened Mikayla's Card Shop in a hospital room in late April.

"I was making a card for someone, and I was so good at it, I thought I'd open a card shop," Mikayla said.

Her nurses bought cards. So did her tutor. Other employees and even friends of employees came to check out her shop. She charges $1 for a big card, 50 cents for smaller ones.

Her mom, Lynda Coenen, takes the orders.

Mikayla's materials are spread out on the tray table over her bed. There are stickers, glitter pens, a set of decorative-edge scissors and sheets of brightly colored construction paper folded in half.

She's been given craft supplies as gifts, including a card-making kit from a nurse.

"People are so nice," Lynda said. "It's made it fun for her."

The hospital has been a home away from home for the family from Warwick, she said. Each treatment keeps Mikayla at the hospital for up to a month.

Mikayla was diagnosed with leukemia in December, after a week of vague, flu-like symptoms. Stomach pains sent the family to the Mercy Hospital emergency room in nearby Devils Lake. She was immediately sent to MeritCare in Fargo.

Her first admission was tough, Lynda said. She was in intensive care three different times and was placed on a ventilator. But the last three chemotherapy treatments have gone well.

During treatment, Mikayla is often able to leave the hospital on a pass. In April she visited the Children's Museum and the Ronald McDonald House. But then her temperature spiked. Mikayla looked on the bright side.

"Yeah!" she told her mom. Now she could make more cards.

"She had work to do," Lynda said.

Mikayla has talked about opening a card shop when she grows up. She told her mom she would donate some of the money she earned to charity, specifically to parents with kids in the hospital.

"Some people might need it," she said.
