Your plants are too young to get any clones from. Typically you would want to take a cutting that is at least 5 or so inches long to have a good chance of the clone surviving.
When you take a cutting make sure you have a branch that has a bud site at the tip. Don't try to clone the fan leaves.
When you are cutting your clones keep your scissors and gear clean. I use rubbing alcohol to help keep things sterile.
After you take your cuttings keep them WARM and keep them moist. They love the heat and humidity. Some people use a heat pad to help promote root growth.
Hope that helps
