Take up the offers to have some one show you, it's one of those things that you either can or can't learn from books depending on how your mind works -- not an insult, just an observation on how people process information. If your nearby 'Catter's schedules don't fit with your timetable, how 'bout stopping by the coffee hour at a local house of worship or old age home, or some other place haunted by elderly women. I'm sure one (or more) of them would be delighted to help you. You'd learn have the fun of learning, they'd have the joy of teaching, and you both would have a new friend.
