Not exactly a tutorial, but I finally got around to going through my seed ears of my Oxbow Mixed Flint which is basically a Cascade Series redux. I interplanted Cascade Ruby Gold, Cascade Creamcap, Byron Yellow Flint and Abenaki. Partially because I wanted to reselect the whole shebang for my own enjoyment and partially because I wanted to see what the parent varieties were like after reading about them in the Resilient Gardener.
In the spirit of a tutorial. I recommend doing this outside or putting down a lot of cloths or tarps if you must do it indoors as kernels go flying and silks and chaff get all over the place.
