Christa asked how I know what's edible. There are only a couple of wild plants that I know are safe (and only in my own yard where I know they haven't been sprayed with weed-killer). Everything else I leave alone.
Speaking of weed-killer, I need to mix some up and spray a couple of places in my yard. I also need to mow again, and do a couple other bits of yard work. But knitting is so much more fun! Besides, it's a little too windy to spray anything.
