Hello and welcome! I have a small backyard greenhouse, and I work with many seeds, including coleus and snapdraogns, so I understand about working with itty bitty stuff. Here's what I do: I have a 12" x 12" plastic tray that came with one of those mini-greenhouse kits. I line the tray with a seed starting mix, mist it over to go ahead and settle the soil, sprinkle the seeds on top, cover the seeds only slightly and mist gently again. Keep the soil moist, but not too wet. After most of the seeds have germinated, I set up single pots for each baby plant. Using a plant label or stick(or plastic spoon) I pry out as many of the largest seedlings as I can and place them in their own pot. I then reluctantly discard the punier seedlings. I know it sounds like a lot of work, but it works.
