Martinborough local Genevieve Nightingale, 9, said her Field and Sky painting ended up too dark, so a friend suggested it would work as a dusk evening. "So I painted on a sunset and some clouds."
Her painting sold for $20, after she put her own bid on at $15 to push the action.
Her sister, Evangelina, 7, painted a can of tomato sauce, surrounded by tomato vines.
"But I might of not spelled 'tomato' correctly," she said.
It turned out it was; but 'sauce' wasn't.
In total the children's artwork raised $96.
Organiser Glenys Hansen said it was a quieter event this year.
In previous years it has raised about $2000.
"We thought there had to be a better idea than garage sales," she said.
"It's not a big money maker, but it's a win-win for artists in the area."
She said nine artworks sold over the weekend.
