I`ve had a couple left-handed students.
So I tell you what I told them "Play what feels right for you"
If you feel comfortable playing right handed then do it.
If you feel comfortable playing left-handed, don`t let anybody tell you otherwise.
I saw a book for left-handed players in my local guitar shop, it has chord diagrams and pictured chords.
I have to say that one of the best students I ever had, was my left-handed student.
So, keep up the good work.
