Summarize this article:

It should be damp, not dripping wet. Take the tip of the toothpick and poke a couple of your seeds, they should stick onto the toothpick without falling off. Flick the top of the toothpick (not the seeds) with your middle or forefinger. The strawberry seeds should fall off and scatter into the cup. Do not push the seeds down.

Summary:
Fill a cup, jar or other container with soil suitable for growing strawberries. Dip the toothpick in water. Once about five to seven seeds have stuck to the toothpick, hold the toothpick over the soil-filled cup. Repeat several times until all of the seeds are in the soil-filled cup (or container).
