She started the knitathon after reading in the Advocate about children in need in the district.
"I was reading articles about children who need warm clothes and I thought, 'how can I help?'" Mrs Brechelt said.
She took her knitted coffee warmers to Lynda Gibson at Columbus Cafe, who said "bring it on" and agreed to sell the coffee warmers to customers.
Rabbits, dolls, clotheslines, caterpillars, little boys and girls, flowers, hedgehogs and even taniwha kept her busy, and the more she knitted, the more complicated they became.
"I absolutely loved it," she said. "You feel like life is worthwhile when you're doing something like that."
Ms Gibson said it was a fabulous effort from Mrs Brechelt, and she had raised a lot of money for Barnardos.
"She is a wonderful, caring woman and is quite cross that she cannot continue, but the pain is just too great now," Ms Gibson said.
There are only a few of the coffee warmers left at Columbus so anybody wanting one had better get in quick.
