From the solobuch.pdf, I learned to play the first song, quite simple and sound nice.
Also learn a second song in F key on page 8, this gave me some ideas on the finger picking patterns on ukulele.
I can certainly use these patterns on a lot of other songs I used to play with other instruments.
(all this during my lunch break at work, I bring my uke with me in the car, it's so small to practice in the car).
