You can play "Boxer" type fingerpicking--th,i,th,i,th,i,etc. You can also play it th,i,th,m,th,i,th,m,etc.

You can play "Freight Train" or "Don't Think Twice"--(th/m),th,i,th,m,th,(th/m),th,i,th,m,th,etc.

You can almost endlessly vary the above by; 1.changing the order of the alternating fingers, 2. not always pinching th/m (use just "th" sometimes). 3.adding hammer-ons and other frills.

When I was a kid my brother watched me play "Don't Think Twice" in the above mentioned way and suggested that I add interest to it by playing it; (th/m),i,m,th,m,i,(th/m),i,m,th,m,i,(th/m),i,m,th,m,i,etc.
