It was her wish to educate people about cancer and find ways to help with costs.
The executive director of the quilt show contacted them with the idea, and since than, they have raised more than $50,000.
"This is a perfect tie-in with Wendy and our interest," said Cindy Pierce, secretary of the foundation. "And to raise money to help people with their expenses."
Some of the funds help pay for things not covered by insurance, including gas and grocery cards, utility bills and over-the-counter medications.
Some of the works are from as far away as Russia and South Africa.
Wendy's Wish will be auctioning off some of the postcards in frame on Friday at Sisters High and on Saturday at the quilt show at 3 p.m.
