All you'll need for this is to save some toilet paper tubes and keep around a small container that you don't care about. In this case, I used an old Glad Ovenware that I had bought and lost or destroyed the lid to.
First, you'll cut your toilet paper tubes in half, like this:
Then you'll set them in the container like this:
Then, go ahead and fill them with your seed starting mix! After this is done, I add water, but not directly to the dirt, but to the outside of the container surrounding the little tubes. The water will soak up through the toilet paper tubes and into the dirt.
After everything looks like it's moist, go ahead and plant your seeds! When you're ready to plant, you can either choose to leave the toilet paper tube in place or just rip it and it will come right off. I'm going to take mine out only because I don't know how fast they'll decompose. Perhaps I'll leave one or two as an experiment. :)
