Congratulations on the license Mike.
There are basically three types of sheet to tiller steering.
1. boom end or a line tied to the main sheet and back to tiller.
2. foresail clew or a line tied to the foresail sheet and back to tiller.
3. rig an extra foresail (small jib or yankee) and bring a line from the clew back to the tiller.
I settled for the second method after a bit of experimentation.
I downloaded EVERY youtube and studied them before I started.
There are some really good explanations out there.
Here is what I came up with.
