Definitely a case of spinning flax to gold:

Linda started her online business, the Prairie Tumbleweed Farm, as a joke. It was 1994 and she wanted to teach herself how to design a website. Since she lived on the prairie in southwest Kansas, where rolling tumbleweeds are sometimes the only dynamic feature of an endless flat horizon, she invented a farm that sold tumbleweeds, listing prices at $15 for a small one, $20 for a medium and $25 for large.

Which now apparently brings her something north of $40,000 a year. At first this might seem like easy money, but catching, packing, and shipping the things doesn't sound as if it's a breeze. Let's hear it for the market!
