What I did for the Salvia seeds was to soak them in small desert dishes (the same for the others also) then place a paper towel into a cereal bowl, dump the seeds into the paper towel, the water ends up in the bowl and the seeds end up suspended in the paper towel. That keeps the seeds dry enough so that when the wet tip of a tooth pick or bamboo skewer is just touched to them it will pick the seeds up one at a time.
I needed the tissue to see where I was placing the seeds in the dark compost, plus I found the tissue acted as a wicking agent to suck the little seed off the skewer and hold it in place. I could actually turn the tissue over and the seeds would stay in place.
Edited to say that the seeds in the picture are Butterfly weed seed, the salvia were much smaller and I was not sure they would show up in the picture.
