Grow Great Grub has an idea for simple seed starts in cardboard tubes.  I collected toilet paper and paper towel tubes (cut in half) since I saw the idea, and here they are all filled up.  You tie a little group together for some stability, and then just fill it with dirt.  No closing of the bottoms is required.  The dirt stays in fine.  I am very pleased with myself for thinking of (or rather, remembering that Martha Stewart thought of) using a cut off juice bottle top for a dirt funnel.  The wide-mouth juice bottles fit exactly perfectly into the tubes.

The idea is that you can just transplant the whole tube and it breaks down pretty readily.

I’m a little late with the starts, but I’ve got eggplant, poblano peppers, pattypan squash, lemon cucumbers, normal cucumbers, yellow pear tomatoes, beefsteak tomatoes, zucchini, and pumpkin.
