Harvesting Squash Seeds

Just imagine if every time a fruit or vegetable filled with seeds was scraped clean of the seeds, but not just to throw away or compost, but to clean, dry, and store for planting. I know of some folks who make their living with the cottage industry of doing just that. Buying rare exotic fruits and vegetables, meticulously harvesting the seeds, then selling them in very professionally packaged products. What a creative way to be your own boss!
