Planting an avocado seed is beating me

Which method, toothpicks in a glass of water? That one's slow and it's where most people give up. It can take 4-8 weeks before the seed splits and a root shows, sometimes longer. Fat end down, only the bottom third in water, and change the water every few days so it doesn't go cloudy and rot. Warm spot, out of direct sun. Quicker for me was peeling the brown skin off and wrapping it in a damp paper towel inside a sandwich bag, kept in a cupboard and checked weekly. Once the root is a few inches long and a shoot appears, pot it with the top half of the seed above the soil. Don't expect fruit though. From seed it's a houseplant for years.
