It's very easy to do. Just take a damp (not wet) piece of paper towel, put the seeds on it (wrapping or folding the paper towel over them) and either place it in an unsealed plastic bag or small plastic container. Don't forget to mark the bag or container with the variety of seed! Then place the seeds in a warm spot, about 70 degrees is good. I put mine on top of the radiator covers. The seeds will sprout in a few days. You need to check them at least once a day to make sure they aren't dried out.
Once the seeds are sprouted, carefully put them in a soil less mixture in a pot. You need to handle them gently to insure you don't damage the root. I use a pair of tweezers and gently grab them by the root. I usually take a piece of paper towel with the root.
