Newspaper, wrapped around an empty soda can, makes a great seedling-starter.
1. Cut a 6" X 17" strip.
2. Wrap it around a can.
3. Pinch the bottom in four places. Fold them into the middle, in a pinwheel shape. Press them to fit the dome-shaped dent on the can.
4. Take the paper off the can. Fold the edge inwards.
5. Fill with soil.
6. Plant seeds. For tomatoes I favor about 1/2 potting soil to 1/2 sand.
7. Use a plastic bag in a shoebox as a caddy.
8. Mix 1 tsp. of 3% Hydrogen Peroxide mixed with 1 quart water. Water each can-cup with about 2 Tablespoons.
9. Cover loosely with saran wrap or loosely fold over bag.
10. Place on top of fridge for 8 days.

(Couple weeks early, but still had to be said.)
