"It's always just a few bibs and things in a bag," she said.

She trawled the internet for more interesting offerings and found herself drawn to cakes and tricycles made of nappies and other baby gear.

"I saw the three-wheelers on the internet and thought I'd give it a go," she said.

Her first attempt was made of her son's leftover newborn nappies.

"I didn't have enough for a three-wheeler so I tried a bicycle instead," she said.

The trial was so successful she thought she would advertise her wares on Facebook.

Less than a week after she first advertised them, she has already received orders from all across Australia.

"I've got an order from Brisbane and an order from Cowra," she said.

Most of her business has been from the North West, however.

"I think it's been because Mount Isa is so limited in what you can buy for baby showers," she said.

The bicycles include a plush teddy, two wraps, two bibs, a pair of socks, two face washers, 36 nappies and a water bottle filled with lollies for the mum.

Mrs Hartwig is already considering ways to expand her market beyond Facebook.

"I've got a friend who wants me to put them in her hair salon to sell and I've thought about going to the baby supply shops," she said.

It's not just a money making venture - she said building the nappy creations was her "downtime".

"At first it was frustrating and it took a lot of patience, but its a good way to keep busy," she said.

The first bicycle she put together took three and a half hours of trial and error but she said she now has the process down to an hour.

"It's all quite fiddly," she said.

"It's the first time I've ever done anything like this before; the most creative thing I've done is scrapbooking."

Mrs Hartwig is now trialling cakes and bouquets of flowers made of nappies and baby gifts.

Her first order will be ready to be picked up later this week, but she has already given her original creation to her friend.

"She loved it," she said.

"She didn't want to pull it apart."
