In the past, I've made seed pots out of old cardboard rolls, but this year, I found a little wooden pot maker (like this one) to use with newspaper, and strongly prefer the resulting pots. They are sturdier and I think the newspaper will disintegrate better when they're planted in the garden.
Some of these seeds came from my favorite Bunte Forellenschluss, with the life inside waiting, like a djinn in a bottle, for the magic of light and water. In the Talmud, there is a line that says "every blade of grass has an angel that stands over it and whispers 'grow,' 'grow.'" I like to think of all the angels invited into my home, thanks to the sacred magic in those seeds.
