[edit] Steps

Find the perfect hill. Not too steep, not too flat. Make sure it's smooth, and doesn't have too many bumps or obstacles.
Learn to go down the hill by leaning on your toes and heels one after the other. This will let you turn as well as control your speed. Don't attempt this if you don't know how to make a basic turn.
Move to a flat area to learn how to carve after you've learned how to go down a hill.
Practice carving on flat ground by leaning on your front foot. Then push the back of the board to the right on your heel side. This will turn you left just like snowboarding. Then try turning left by pulling with your toes left.
Go out to your hill and try carving now!

[edit] Tips

Remember to always wear safety gear!
Freebording is not skateboarding, even if you are the greatest skateboarder it is nothing like it. Snowboarders have a much better chance at learning faster!
You have to realize that you are boarding on land not snow, it hurts a lot more!
Watch others freebord. It will help you to learn the basic movements. Try sites like Video Google and
Once you can carve you can stop, just turn your board one way more then just a carve, it will skid you to a stop.
Have fun and move to new hills, freebording can be fun but also very hard!
