How to grow a new bonsai off of cuttings?

A bonsai that I have just lost a large branch about 5 cm long. Since I don't want to just throw this big branch away, I was wondering if I could grow a new bonsai from it. Someone told me how to, but I forgot. The branch is about a centimeter thick, and it is from a jade bonsai. I read in one place to dry the branch out and then plant it, but another said to plant it right after it has been cut. Help?|||Let it dry out for 4-7 days approx, then plant it. If left to its own devices, it will grow into a normal sized jade plant. Bonsais are created by judicious pruning of branches and roots, try google for some tips.
