Thanks for the kind words!
My biggest "discovery" was that, if I grow and collect LOTS of seeds, cleaning becomes much easier. I just keep whatever falls easily out of the flowerheads, and throw the rest away. No chaff, no dust.
I made some tiny scoops for dust-like seed. Soda straws, slit and wrapped around a chopstick or bamboo skewer or thin wooden dowel, then taped down. If you only tape the plastic to itself, not to the bamboo, you can slide the plastic straw in or out to make the scoop bigger or smaller.
But now I like the stainless steel 1/64th tsp I got from Amazon, instead of soda straws. The only exception would be if I cut the soda straw to a sharp point. That lets me pick up a TINY amount of seed, then tilt the chopstick up so the seeds are held safely in the "scoop" part, instead of falling off the edge or tip.
